Hi I am a new member. I am worikg towards the DSP based controller for FRONT END CONVERTER. I want to find the parameters for the PI Controller. My guide suggest to find references for unity modulus method. I am unable to find so. Cn any body help me for the same?
Thanks

 

You can search for PID tuning methods.
There you will find Ziegler-Nichols and Cohen-Coon.

There are formulas for PI only mode.

 

Hello,

Here is a page with links about P PI and PID controllers.

There are also links for other control systems.

From my understanding, you turn off the integral gain first and slowly increase the proportional gain. The proportional gain will give you overshoot and fast response, along with steady-state error. If you're fine with a bit of overshoot and the response, then you can start bring up the integral gain. You should try to get it 'critically' damped, which implies not much overshoot and decent response times. You will eliminate steady-state error with the integral gain.

PID is another story..
