I guess the controller is supposed to be placed between E(s) and plant G(s), because in the problem I attached, it says 'unity feedback' which means H(s) = 1. All I got is identical to the one I attached. I'm many times bothered due to lack of explanation and sources regarding exercises in...

Thanks for reply. In fact, I'm still unclear about the part (G(0)/(1+Kp*G(0))=1) which is from the solution. In the problem, they just gave me the condition that 'PI controller with a unity dc gain' and in the solution, the equation '(G(0)/(1+Kp*G(0))=1)' just came up. The equation is not...

I'm doing my homework, and encountered a problem. The problem is the one as attached. It includes a part of solution that I don't understand. I've known that when designing the PI controller, we start from D(s) = (Kp + Ki/S) The condition of the PI controller is, firstly, unity DC gain. So...
