■10, you don’t need to sketch the root locus. I want to know the steps to find out b and k. 2. Consider the system shown in the figure below. It is desired to design a PID controller Gc(s) so that the dominant closed-loop poles are located at s = —1 ± fa For the PID controller, choose a =1, and then determine the values of K and b. Sketch the root-locus diagram for the designed system.
