A unity negative feedback system with Gc(s)G(s) = K(s + 2) / (s(1 + ?s)(1 +2s)) has two parameters to be selected.
Determine and plot the regions of stability for this system.
Select f and K so that the steady-state error to a ramp input is less than or equal to 25% of the input magnitude.
Determine the percent overshoot for a step input for the design selected in part (b).Use MATLAB to plot y(t) for a step input R(s).
