Part – B (3X10=30)

                                                

6.    A unity feedback control system is characterised by       [CO1, HOT/K5]

Determine the gain ‘K’ so that the system will have dam[ping ratio of 0.5. for this value of K determine Rise time, peak time and Peak overshoot along with natural damping frequency.

7.      Derive the transient response of Under damped and Critically damped second order system

       [CO1, HOT/K4]

8.    The system has time response of

for unit step input. Find Undamped natural frequency, Damping ratio, Rise time, Peak time and Peak overshoot                         

                                                                                                            [CO1, HOT/K4]
