This set of Control System 2 Multiple Choice Questions & Answers (MCQs) focuses on Control System II Set 4

Q1 | Consider a system if represented by state space equation and x1 (t) =x2 (t), then the system is:
  • controllable
  • uncontrollable
  • observable
  • unstable
Answer: uncontrollable
Q2 | A transfer function of the system does not have pole-zero cancellation? Which of the following statements is true?
  • system is neither controllable nor observable
  • system is completely controllable and observable
  • system is observable but uncontrollable
  • system is controllable and unobservable
Answer: system is completely controllable and observable
Q3 | The impulse response of a linear LTI system is given as g (t) = e(-t)The transfer function of the system is equal to:
