DC Motor Speed Regulation-14th week

DC Motor Speed Regulation report

The original controller contains only proportional links. We add integral and differential links and are designed as PID controllers. The code is as follows:

algorithm    error:= command.signal[1]-  feedback.signal[1];    I_error:= i_error+ error;    D_error:= error- pre (error);    Pout:= Kp * error + Ki * i_error + Kd * D_ERROR;

The parameter values are adjusted in the order of proportional link, differential resolution and integral link. The final selection parameters are as follows:

    Parameter Real kp=6;    Parameter Real Ki=0.1;    Parameter Real Kd=+;

The results obtained (0-5S) are as follows:

　　

Calculate the dynamic parameters of the response (0-1.1s results are easier to observe):

The calculated MP is about 22%, the response time is about 0.12s, and the response performance is better.
