I myself am working on a PID controller for a robot and I must say: this was a really good video, very clear explanations and useful examples. Nice job!
21:40 steady state error 25:47 to avoid algebraic loop error , tick the checkbox in PID block parameter which says "PID controller is in a conditionally executed subsystem" 25:47 PID tuner app can only be used if time domain is continuous
im getting this error: Error:Error in 'motorDistCtrl_soln/Motor/Motor': Failed to evaluate mask initialization commands. Caused by: The "LTI system variable" parameter of the LTI block must be set to a valid LTI model. anyone else? did anyone resolve it?
can someone please help me , how can i tune PID controller for same 1 meter distance but also for backward motion and then add it to my model. i have created logic in same state flow chart so that robot moves backward after a break of 1 second but now i want to use PID controller because it goes beyond 1 meter while moving forward and backward. in these video stateflow chart has been replaced by PID but in my case what should i do? bacause my Logic for 1 meter forward and backward is in Stateflow because of that i cannot replace it simply. where can i place PID in my Model and what value(reference and measured) should i tune with?

It's a filter coefficient for the derivative term. Since there is no "true" derivative in a discrete algorithm, usually it's approximated with a first-order transfer function (or low-pass filter) where N affects the cutoff frequency.
Try some commands workspace mex-setup This will show is their any compiler installed on your system . If not then install then minGW 64 compiler . Then run command mex-setup and choose the. Appropriate compiler c++ Then run command mex sfun_time.c

@@xiaonan238 Wow! Yes I found it,thank you soooo much!
@@xinwenzhang4150 may I use my own transfer function of dc motors of my robot ?
how to set up the lookup table? can anyone help?
What is the physical meaning of filter coefficient N?
It's a filter coefficient for the derivative term. Since there is no "true" derivative in a discrete algorithm, usually it's approximated with a first-order transfer function (or low-pass filter) where N affects the cutoff frequency.

@ANURAG KUMAR have you found how to set the look-up table? am facing the same problem here maybe you can help

s-function error , ANY HELP
Try some commands workspace
mex-setup
This will show is their any compiler installed on your system . If not then install then minGW 64 compiler .
Then run command mex-setup and choose the. Appropriate compiler c++
Then run command mex sfun_time.c
