Question 1
A PD controller is used to compensate a system. Compare to the uncompensated system, the compensated system has
Question 2
G(s) = (s+a)/(s+b) is a lead controller to obtain maximum phase lead of 30⁰. The values of a and b are
Question 3
The transfer function of a PID controller is given by
as 
tends to zero
as tends to zero Question 4
A unity negative feedback closed loop system has a plant with the transfer function 
and a controller Gc(S) in the feed forward path. For a unit set input, the transfer function of the controller that gives minimum steady state error is
and a controller Gc(S) in the feed forward path. For a unit set input, the transfer function of the controller that gives minimum steady state error is Question 5
A control system with a PD controller is shown in the figure. If the velocity error constant KV = 1000 and the damping ration ζ = 0.5, then the values of KP and KD are:
Question 6
The transfer function of a first-order controller is given as
Where K, a and b are positive real numbers. The condition for this controller to act as a phase lead compensator is
