    Quite helpful. PID system and control greatly affects how a system perform and long after it has started up into operation. A not properly tuned PID System can be the bane of some operators Plant shift especially with chemical feed systems or pH control system in water system and can cause a lot of issues. A follow up video to this one properly demonstrating with animation as usual how to go about properly tuning a PID could be very helpful. It could show different examples of how you would go about tuning a loop to be Fast Reacting, Slow Reacting, Tightly Tuned, Not so Tightly Tuned etc. That can give people a proper idea how each the PID adjustments affects a tuning for various outcome in its control.

    Howdy. Again very nice.
    Being good with Data Types are a must if one aims to be a pro with PLC:s and analog signals. Let's clear up the PLC jargon.
    PLC jargon. Math jargon. Example.
    Hex. Hexadecimal 7D hex = 125 dec (integer)
    Integer
    Decimal Integer 128 dec
    Real Floating dot value 6,456 x 10 exp 4 (dot in US and comma in Europe).
    Let's assume we use a 8 bit analog input. The input A/D returns a 8 bit Hex Integer value. Now we must check the manual and establish if the return is a + only monopolar value or if it is a + - bipolar value. If the return Data Type is bipolar the highest bit going ON indicates a negative integer. The monopolar span is 0 - FF hex. And the bipolar positive span is 0 - 7F, and the negative span is FF - 80 (ascending eigenvalue).
    Now. The PID function block most likely will need input Data Type to be Real (floating dot). And it most likely will return in Data Type Real too. If we try to connect the analog intut return to the PID function block the programming environment will display Type Mismatch. We need to use a Data Type converting function block in between to convert Hex integer to Real. And the same at the PID return. Real must be converted to 8 bit Hex.
    And observe. The programming environment does not necessarily recognize a Type Mismatch between monopolar Hex and bipolar Hex. One must be aware of the Data Type at every step of programming. If a function block recognizes a monopolar value as a bipolar value results may cathastropic when the value advances from 7F hex to 80 hex. That is a switchover from full positive to full negative.
    Regards.

      Z-N tuning is not a good way to optimize controller gain. The results are awful. This hurts production. I tell anybody that wants to use Z-N tuning to go away and don’t come back until they understand pole placement or another good alternative. Anyone teaching Z-N is suspect.

  • @boys7371
    @boys7371 5 лет назад +3

    good introduction, I am always wondering, instead of use PLC, I actually can use Raspberry Pi, relay, and python programming or node-red to implement PID control. and that is cheaper, easier, able to have more functions. If I am an investor, I really feel the risk of PCL and automation industry

    • @realpars
      @realpars  5 лет назад +5

      You are correct, a Raspberry Pi (or Arduino) controller is much cheaper. However, for even a simple industrial application, an Raspberry Pi controller presents multiple challenges. First, Raspberry Pi analog inputs are 0-5V, whereas the industrial standard is 4-20ma at 24VDC. Analog outputs from the Raspberry Pi are typlcailly PWM, whereas in industry they are 4-20ma. Converters can be purchased or built, but this adds cost and reduces accuracy and reliability. The Raspberry Pi is s 5.1VDC device with low voltage I/O. This low level of voltage operation would be very susceptible to electrical interface in any modern plant facility. The I/O is very low power, and starting large motors or firing inductive loads would require interposing relays. Even the most I/O intensive Raspberry Pi controllers have limited I/O. A plant with 2500 I/O would require approximately 50 networked controllers. This would require an inordinate amount of overhead programming that would outstrip the capability of the Raspberry Pi controller. There are no built-in functions in the Raspberry Pi, so basic functions like PID loops have to be programmed from scratch. And I could go on. I like the Raspberry Pi controllers, and I believe they have a place in small skid-based processes or small device control, but they are not designed for large process control applications.

    • @boys7371
      @boys7371 5 лет назад +1

      ​@@realparsWow, many thanks for your reply, appreciate you took it seriously. I like all of the technology/science parts of PLC, their proposed usages for industrial application. I got it, and I love it. I do use PLC, and I also use RPi and industrialised version of RPis. As you said, there are covert shields, 24V DC, 4-20ma are not problems, the accuracy, precision and durability can be enhanced in many ways. Programming is not a problem for the new generation, programming should be a fundamental skill. Scale problem? if 1 RPi not enough, I can use 100, even cheaper than one S7-1500. look at the container, docker tech, they are designed for scaling up. The concepts of opensource, community development are providing faster development speed, more function integration, rich options of supply. I am worried about the future of the PLC and automation industry if the current players still insist on keeping the closed, isolated approach to develop and sell (marketing) their software and hardware, and soon or later, customers would have 'opensource' options, what level of loyalty are you expecting? The ICT industry is trying to take away the cakes from traditional automation players. Just look GE, Siemens from 2014 -2019. And look Microsoft (Azure IoT), Google, AWS, where are their hands. There is a 'disruptive innovation' happening NOW. just like the time while Ford introducing T line, apple's 1st iPhone, see what Nokia, Kodak responded. You can find more case from wiki about 'disruptive innovation'...I feel it started silently for PLC, for automation, for manufacturing information systems. The war field of the commercial market is brutal, they would tell what they are going to do with you. Just check the latest interview of the founder of Raspberry Pi, read carefully about why they design RPi 4 like this. Is that for commercial use? Industrial use? Dude, I want the PLC and automation people to survive and have a happy life, they are the people far more honest and pragmatic than others, they are trying to solve the problems rather than creating problems ( abuse your data and privacy). I am not saying PLC would totally lose the market, there are many cases still need very powerful industrial control. But can they stand still in the next 5 years, 10 years? I am not sure the flags of 'Industry 4.0' and 'IoT' would help current industry players. What I see, that they are losing the business gradually. Eventually, if these big, old guys die, maybe not a bad thing; it's making new space for more creative and useful products and service. How do you think?

    • @matthewmeuleman3369
      @matthewmeuleman3369 4 года назад

      I enjoyed reading that reply. Especially knowing that arduinos could handle a skid application.
      One other feature of a PLC are the opto coupled relays that are built in, they are more robust as they are tried and tested.
      Plc manufacturers are doing fine not opensourcing their software, to do so, would put their clients and their assets at greater risk of cyberattack. Arduino and raspberry pi target to small scale/ prototyping, their business needs to be open source to catch on, where as PLC manufacturers look at what industry needs and provides it.

    • @boys7371
      @boys7371 4 года назад +1

      @@matthewmeuleman3369 thanks for your reply. Yes, PLC has done much more robust test than IoT open source device. However, we need evaluate the return of robustness, or do you want more functions maybe more useful. the question is very like when iPhone started to fight Nokia. once you connected your device to the internet, game changed lot. closed source would not be safer than open source, for example, Linux system.

      The autotune feature, as you can see in the video, is available on a tab in the PIDE configuration window. Autotune is a separate software product that requires a separate license. Once installed, the configuration items on the Autotune tab will be active and allow Autotune to be enabled for the loop.

    Do you have video that shows differences between two "control actions"? As an example, suppose it is desired to control the temperature by reducing the input power to a heater when PV is greater than SP and increase the input power to a heater when the temperature falls below SP (i.e. take action in both cases).

      RealPars has a much more detailed course on PID control available at RealPars.com. In the course, all three control modes are detailed, and the equations and actions taken by the controller are demonstrated using a TIA Portal ladder program and a Siemens S7-1516 PLC. You may want to check it out!

    Hello! For my project, I have 1 PT and 1 FT to control a flow control valve (FCV), having setpoint of pressure = 8.5 barg and flow = 140 m3/hr. The PT is located before FCV while the FT is after FCV. When pressure reaches

      @realpars  2 года назад

      What you described can be done with 2 PIDE loops setup as an override control scheme. One controller will be set up for pressure control and the other as flow control. You will then connect each output to a "low select" or "high select" block, depending on the actions of your controllers.

    Why is output signal (CVEU) connector to heater but not to control valve?

    • @realpars
      @realpars  2 года назад

      Maybe 'heater' was not the best description for the final control element in this case, but the programmer has the flexibility to tag the final control element by function or by description of the actual device. The important concept is the CVEU (control value in engineering units) is connected to the final control element to give the proper 0 - 100% output as calculated by the PID.

    • @realpars
      @realpars  Год назад

      Thank you for your inquiry. If you're using outdated PLC software lacking math capabilities or software that's over 30 years old, it might not include built-in function block features. Nowadays, most professional PLC software packages come equipped with PID function blocks. I cannot confirm if training software provides these features; you may need to upgrade to a professional version.
      However, if you're proficient in mathematics and your software is up-to-date with the latest math functions, you have the option to create your own PID controller. In essence, a function block simplifies the programming process, where someone else has already designed the program structure, and you only need to input the relevant parameters. The output will then generate results for your output devices or analog and digital cards as required.
      Happy learning!

    what about LQR /LQG Hinf can we use them in plc

    • @realpars
      @realpars  5 лет назад

      Yes, there are those (mainly in academia) that suggest using Linear Quadratic Regulator (LQR) algorithms and Linear Quadratic Gaussian (LQG) algorithms for PID-type control. The common feature of these two approaches is that the gains are dynamically calculated as the process runs. This usually requires matrix calculations, which are not easy to do in a PLC. It is possible, but unless you truly have a process that must be modeled using a second-order process model, it is likely not worth the extra effort, and if it is, a different, more efficient computing device than a PLC to handle the matrix calculations would be a better choice.
