Hi CAN. Very instructive and helpful video. I am working on a project to design the controller of a motor. My question is how do you take into account the actual parameters of your system? For instance, on matlab i get an amplitude of 1 when i introduce my open loop function, while in real life my amplitude was 19rad/s; the stable speed of the motor. Is there a way to modify this on amtlab? Another point is regarding the sensor that feeds the voltage from the plant's output back to the input; How do i take that into account in my design and matlab sim?
Can you please clarify this?. the unit step requires the output to be 1 but the output has an offset always. the case where K=20.8 the system reaches only 0.9 (after settling time). So how do you interprete that?
If the system does not have a pole at the origin (s = 0), meaning having no integrator, then the system with only P controller will always have a steady-state error in closed-loop configuration. That is the reason for using a PI controller to eliminate the offset.

Thanks for your message. You can adjust the gain to go from 19 rad/s to 1 by dividing by 19. I do not understand the other question.
