PID control action for AC reference of variable amplitude and frequency.
i have seen example of controlling output dc voltage of DC to DC buck converter using PID controller. I want to implement DC to AC converter. I tried using PID controller. Since i am comparing output AC signal(continuously varying) with reference sinusoidal signal, PID controller is not providing expected output. In case of DC to DC, both reference signal was constant. In my case, it is continuously varying sine wave. Can anyone suggest any way to get accurate DC to AC conversion? i changed kp and ki parameters to get needed response. it is working well. but, when i change frequency of input reference signal, output signal amplitude drops and again i have to change PID parameters.
P.S. when i change frequency of input reference signal, again i have to change PID gain parameters. Can PID controller work with continuously varying reference signal(in terms of amplitude and frequency both) ?i have seen example of controlling output dc voltage of DC to DC buck converter using PID controller.
