Question 1
(a) i) Dynamic System Modelling is used in the design of control system. List the main steps of this process. (5 marks)
ii) List 5 advantages of closed-loop systems over open-loop systems. (5 marks)
(b)A particular closed loop system has a pair of complex conjugate poles at: s = -3.5 ± j4.2
i)Sketch the pole/zero diagram and state the frequency of oscillation and the system time- constant. (4 marks)
ii)The system gain constant is 2.5, determine the system’s closed loop transfer function and hence calculate the system’s closed loop step response.
