Control System Multiple Choice Questions
Control System Multiple Choice Questions 1) A major part of the automatic control theory applies to the: Casual systems Linear Time invariant systems Time variant systems Non-linear systems Answer: (b) Linear Time invariant systems Explanation: A linear time invariant (LTI) system provides the same output for the same input irrespective of when input is given. LTI systems are also used to predict the system's long term behavior. Hence the correct answer is an option (b). 2) Traffic light system is the example of: Open-loop system Closed-loop system Both (a) and (b) None of these Answer: (a) Open-loop system Explanation: The traffic lamp will glow according to the set timing and sequence and is time-dependent. The sequence and time are controlled by relays that work on the pre-programmed time. It does not depend upon the rush of the road. Hence the correct answer is an option (a). 3) Laplace transform of a step function shown below is: 1 1/s^2 0 1/s Answer: (d) 1/...
