Slow control dsPIC33EP128GS808
I am developing a control for buck converter (Type III controller). I am using the dspic33EP128GS808 in simulink, but I have a problem.
The response time of my control is very slow.
If the time between disturbances in small the control responds fast, but if the time between disturbances increases the response time also increases (taking up to 40 seg to respond).
In the pic I show how I am programming the control.
The Type III controller is discretized with a sampling time of 10us (the switching frequency of the buck converter).
Does anyone have any idea how to make my control faster?
Thanks for your help
