How can I implemented the PR Controller?
显示 更早的评论
Hello I´m ghis, I have a project in which I should implement a PR Controller in Simulink. More precisely I have to impliment the following two functions:
1.
GRP(s) is the transfer function of the PR-Controller (see image)
2.
GHC(s) = is the transfer function of the harmonic compensator where h denotes the harmonic order that the compensator is implemented for.
Please can you help me to implement this two function in Simulink?
@@ The two function must be implemented separately (that mean two Simulink program)
Thank you in advance for ur help.
Best regards

All those blocks are located in Simulink library. You can find them.

You need to define the GPR in Matlab-command line and then give numerical values to Kp and Ki. Then using
GPR=tf([Kp Ki Kp*w^2],[1 0 w^2])
bode(GPR)
command, you can obtain the bode plot of the controller.

The PR Controller is a special form of PI Controller and it does not take place in Simulink Library. In simulink library, you can find a block PID, which is convertible to P, I, PD or PI.
If you check the bode plot of the PR Controller, you will see that the w variable brings a jump at the frequency w. This means that if a system has a zero at that frequency, it can be compensated by setting the value of w wisely. For more information about this, please check Notch Filters.
By changing the value of Kp and Ki, the system response can be boosted or attentuated since due to the numerical values, the bode plot will start below or above 0dB.

Hello @birdman
How PR controller can be implemented in MATLAB 2015a ?
I am trying to use PR controller to implement Cuk converter with SRM drive control.
please share attachement on tejalpatil012@gmail.com
Thank you.

I am Essien Aniefiok Udo, I am working on this same project, implementing a PR controller for a Grid connected inverter, I need assistance in the simulink implementation of the PR controller with harmonics compensators to reduce low frequency harmonics at the output of the inverter
