Teknik Elektro kak

@@kurniawanlearning di teknik elektro mempelajari amplifier clas d atau tracking amplifier clas enggine gitu gk mas. Edisi salah jurusan nih

@@jyloindonesia yg sering dipelajari amplifier class A, B, AB, dan C saja, kalo utk yg class D jarang dipelajari paling cuma intronya saja, itu kalo ga salah amplifier dgn pulsa ya?

@@kurniawanlearning iya kak pakek pwm, kalo filter aktif seperti sallen key, stat variable gitu dipelajari gak kak, aku mau pindah haluan mungkin h h

@@jyloindonesia filter aktif dan pasif juga dipelajari di teknik elektro pada konsentrasi instrumentasi, karena di prodi teknik elektro biasanya dibagi mjd beberapa konsentrasi instrumentasi, otomasi, dan power system. Jika ingin lebih mendalami instrumentasi elektronis lebih baik masuk di prodi elektronika saja. Sbg contoh di kampus tempat saya mengajar ada prodi teknik elektro dgn jenjang S1 dan ada juga prodi elektronika dengan jenjang D3/vokasi. Btw kakak saat ini jurusannya apa?

Terimakasih🙏, semoga bermanfaat

This is an airfoil design optimization project on a horizontal axis wind turbine blade consisting of 3 blades. Optimization aims to maximize the power coefficient (Cp) of the wind turbine while considering its shape so that it has immunity to dust accumulation on the nose of the airfoil along the blades. Dust buildup can change the shape or geometry of the blade airfoil, so that with my strategy, the blade has an optimal shape (immune) even if dust buildup occurs. To transform the airfoil (2D) into blades (3D) to get the Cp value, I use the Blade Element Momentum Theory (BEMT) formula. This script is made using Matlab R2015b. 1. Install XFOIL.exe, as an airfoil lift and drag coefficient evaluator. 2. Open and run the file "MAIN" which has the extension MATLAB Code, then a GUI window will appear. 3. In the GUI window, there are START and RUN buttons. - START button to start the optimization program. - RUN button to continue running the optimization program when it crashes caused by XFOIL not being able to read the irregular airfoil shape due to randomness at the mutation stage. 4. To stop the program, please type Ctrl+C in the MATLAB "Command Window". This is a little hard to do, because XFOIL.exe tries to block the MATLAB window. Sorry, but this GUI is not yet perfected. This optimization process takes a very long time, because the MAIN program script has to call many functions such as (crossOver, mutation, fitnessEvaluation, etc.) and call the XFOIL.exe software every program loop, this is only for personal projects. Additionally, if you can evaluate the airfoil using a model that can be scripted in MATLAB, then you don't need to use XFOIL.exe, and the program will run very fast. Here is a link to the MATLAB file you asked for, hope it helps. Greetings from Indonesia... drive.google.com/drive/folders/10_bjTKf0XTVSqrKxw5x0tJRKR_mOWxHq?usp=share_link

Thank you very much. What I want to do is airfoil optimization. Multiple inputs and outputs are similar to this one. Can you add your Facebook or twitter account?

​Wish all the best wishes for you.

@@chaoqiu3384 glad to help, you can also optimize the airfoil in a simpler way, for example take the NACA2412 airfoil : First digit is max chamber = 2%, range (0 - 9.5%) Second digit is max chamber position = 40%, range (0 - 90%) Third & fourth digit is thickness = 12%, range (1 - 40%) You can optimize the three parameters above in each range.

thanks, for you too.

Cakep suaranya
