List of top Electronics and Communication Engineering Questions on Control Systems asked in CUET (PG)

Consider the following frequency domain specifications required to design a control system: 
A. Bandwidth 
B. Gain margin 
C. Phase margin 
D. Maximum overshoot 
Choose the correct answer:

Match List-I with List-II (Compensation vs Characteristics).

A minimum phase unity feedback system has slope $-20\,dB/decade$ for all frequencies. The value of maximum phase margin is:
The steady-state error of a Type 1 system for a unit step input is:
Which of the following are listed as types of compensators for system design? A. Lead compensators B. Stepper motors C. Lag compensators D. Servo valves
According to Nyquist stability criterion, the number of unstable closed-loop poles (Z) is equal to:
Assertion (A): Feedback control systems offer more accurate control over open-loop systems. Reason (R): Feedback establishes a link for input-output comparison and correction.
Arrange correct sequence of time domain specifications of a second order system in ascending order of values: A. Rise time B. Settling time C. Delay time D. Peak time
Assertion (A): With lag-lead compensator, the bandwidth of the system is not affected much. Reason (R): The effect of lag and lead compensation at high frequencies cancel one another.
