In the system shown in figure below, the sensitivity of the closed loop transfer function w.r.t. parameter a is
For the system shown in figure below, is equal to (where, T = closed loop transfer function)
For the closed loop transfer function shown below, E(s)/R(s) is given by
Consider the following statements:
1. Closed loop system is less sensitive to variations in feedback path parameters than variations in forward path parameters.
2. Feedback can improve the stability or may be harmful to stability if it is not properly designed and applied.
3. Feedback controls the time response of the system by adjusting the location of poles.
Q. Which of the these statements are correct?
An unity feedback control system has a transfer function of The open loop transfer function of this system is
Assertion (A): Feedback in control system improves the time response of the system.
Reason (R): Time constant of an open loop system is less than the time constant of a closed loop system.
For the unity feedback system shown below, if the input to the system is a unitstep signal, then the integral square error (t) dt for infinite value of gain k will be
