Reference Tracking//DC Drive
显示 更早的评论
Hello everyone,
i am working on a design of a controller for DC Drive. the closed loop has a negative state feedack using LQR method and a PID controller.
with reference speed set to 20 rad/s, i have two issues that i could not solve since days
- the system response doen not change whatever tuning of PID or feedback gain are changed
- the signal diamensions cannot be adjusted by changing the gain multiplication parameters
- why the steady state speed is not 20 rad/ s but 35 rad/s unstead ?
Thank you for your feedback.
*sampling time 14 ms (no alliasing)

Please refer to PID Controller block which will give efficient result. Also please refer to following link to use LQR method in Simulink:-
