Which of the following controllers improves the transient response of a system? Correct Answer The derivative controller

Effects of Proportional Derivative (PD) controllers:

  • Decreases the type of the system by one
  • Reduces the rise time and settling time
  • Rise time and settling time decreases and Bandwidth increases
  • The speed of response is increased i.e. the transient response is improved
  • Improves gain margin, phase margin, and resonant peak
  • Increases the input noise
  • Improves the stability

 

Effects of Proportional Integral (PI) controllers:

  • Increases the type of the system by one
  • Rise time and settling time increases and Bandwidth decreases
  • The speed of response decreased i.e. transient response becomes slower
  • Decreases the steady-state error and steady-state response is improved
  • Decreases the stability

Assertion (A): All the systems which exhibit overshoot in transient response will also exhibit resonance peak in frequency response. Reason (R): Large resonance peak in frequency response corresponds to a large overshoot in transient response.
Assertion (A): It is desirable that the transient response be sufficiently fast and sufficiently damped. Reason (R): Oscillations are not tolerated in the transient response.
