Time: 02:30 PM TO 05:00 PM Total Marks: 70

Instructions:

1. Attempt all questions.

2. Make suitable assumptions wherever necessary.

3. Figures to the right indicate full marks.

Q.1 (a) Discuss the Optimal control systems in detail with necessary equations. Brief
about the procedure to find out feedback gain for the systems using it.
07
(b) List the steps to design Robust PID controlled systems. 07

Q.2 (a) Explain the Pseudo Quantitative Feedback Theory, with suitable example 07
(b) What is dead beat response? Give the design procedure for obtaining dead beat
response.
07
OR
(b) Explain the duality principle of controllability and observability, with suitable
example
07
07
Q.3 (a) State the condition for observability. Discuss the state observer design with
necessary equations and block diagram.
07
(b) With example discuss design of digital controllers using root locus in the z-plane. 07
OR

three states, find out the dimensions of the various matrices of the state model.
07
(b) Explain the compensator design with integrated full-state feedback and observer. 07

Q.4 (a) State an Ackermann's formula. Show the Computation of State Controllability
and Observability using it. What is its limitation?
07
(b) Discuss about Internal model design for step input tracking with mathematical
arguments.
07
OR
Q.4 (a) Explain the implementation of digital ( PID, PD and PI) controllers with
necessary steps.
07
(b) What do you mean by Eigen value and Eigen Vector? What is the role of its in
State Variable Analysis?
07

Q.5 (a) Discuss the Lead compensation technique based on frequency response (bode
plot). List the necessary steps and explain with suitable example.
07
(b) Discuss importance of robust control system and sensitivity of control system. 07
OR

Q.5 (a) State the Computer ( MatLab) commands used for State variable analysis with
syntax/code and its related outputs. Mention appropriate comments also.
07
(b) Explain the control of uncertain parameter in robust control system. 07
