PARTA

1. Design a suitable compensator for the unity feedback system with forward 9
10

transfer function © (5) = s(1+s)(4+0.1s) without changing the gain crossover

frequency to achieve a phase margin of 600 and steady state error of 0.01 for

unit ramp input.

‎2. Consider the unity feedback system © (5) = ദോ Design a compensator 5
that will yield Kp=20 without appreciably changing the dominant pole location that

yield a 10% overshoot for the uncompensated system.
10

b.Design a ‏,م‎ Pl and PID controller for the unity feedback system © (6) യമു by
applying Zeigler_Nichols tuning method.
3. Design a P or PD or PID controller for the unity feedback system with forward 9

250
transfer function © (5) =s(s+1)(s+25) to reduce the settling time by a factor

of 4 while continuing to operate the system with overshoot 25% for unit
step input and reducing the steady state error to unit ramp input to zero.

PART 8

4. ദ. Design a state feedback controller for the system to place the poles of the system 2

at -1+j0.5 for the system * = X + = [0 16.
