Hi everyone, I´m currently doing my thesis in Pitch Control using MPC, but before that i need to implement a functional PI control for torque and pitch angle. I´m doing basically this:
-I track lambdaOpt, getting GenSpdRef from it, then i get the GenSpdError that´s the input for the torque (power) control. By doing it i l try to control the power ate a constant zero pitch.
-Here is the problem, my pitch controller is also a PI, that has is MaxLim ate 90 deg and a MinLim at a value that is function of Lambda, so it is always changing. The problem, i think, is ate the PI control because Simulink crashes when power takes its rated value and the Pitch control starts to operate. I dont know if anyone can help with just this information, but there´s something that i dont understand in this image that i post.
Here i send some images of my controlers and the state machine that i use to swope between one and other. Thanks for your help.
This forum if for discussing controls. Questions about how to implement controls in FAST are more appropriate to the CAE Tools forum.
