This is a cascade control block diagram. Kc2 and 1/(s+1) are controller and sensor for inner loop. (a) If we specify Kc2=2,1=5, show the range of Kc1 to make closed-loop system stable. (b) If we specify Kc2=10,1=5, show the range of Kc1 to make closed-loop system stable. (c optional) Use Simulink to build this control block and tune inner and outer controllers. Determine Kc1Kc21 and calculate the settling time, decay ratio, overshoot, offset
