  • Question

  • Consider the systems with following open loop transfer functions

    1. Consider the systems with following open loop transfer functions If unity feedback is used, the incr
    2. Consider the systems with following open loop transfer functions If unity feedback is used, the incr
    3. Consider the systems with following open loop transfer functions If unity feedback is used, the incr
    If unity feedback is used, the increasing order of time taken for unit step response to settle is


  • Options
  • A. 1, 2, 3
  • B. 3, 1, 2
  • C. 2, 3, 1
  • D. 3, 2, 1

  • Correct Answer
  • 2, 3, 1 

    Explanation
    Consider the systems with following open loop transfer functions If unity feedback is used, the incr. For the three systems the values of ??n are 1.8, 2.5 and 2 respectively.

    Hence values of T are 0.55, 0.4 and 0.5 respectively.
