All the closed-loop responses are now satisfactory. For comparison, examine the response
when you use the same controller at all operating points. Create another set of closed-
loop systems, where each one uses the C = 2 controller, and plot their responses.clsys_flat = feedback(Plants*Controllers(:,:,1),1);figure
