Question Paper
What do you mean by feedback control system Distinguish between open loop system and closed loop system.
Define the following:
Rise time
Peak overshoot
Steady state error
Delay time
2. Establish correlation between frequency domain response and time domain response.
3. Sketch the root locus plot for the system when open loop transfer function is given by
s +4s .
4. Sketch the Nyquist plot for the system having
1+4s 2s)
Explain the meaning and significance of phase margin and gain margin of a control system. How will you obtain the values of these margins from Bode plots?
What is meant by relative stability? Can you find out relative stability by Routh stability criterion?
Comment upon the application area of Lag Compensator. Give a simple RC circuit to implement it. Derive its transfer function.
Determine the value of k such that the roots of the characteristic equation given below lie on the left of line s -l.
s^3 10 s^2 18 s k 0
7. Draw the Bode plot for the transfer function given below:
48 +2·4s+16)
Explain the function and working of an a.c. servo motor.
Discuss the effect of feedback on stability, noise and overall gain of the system.
9. Write short notes on any two of the following:
Transducer and Transport Delay
Proportional Integral Controller
Computers Electronic Design Aspects
