(a) (b) (c) Explain how the concepts of observability and observer are used in conjunction with control system design. [4] Explain why it is important to use closed-loop observers in modern control designs? [2] Consider the following open-loop plant. ii) It is required to design an observer, which operates with 10% overshoot and a 1 second peak time. i) iii) G(s)= iv) (s+ 6) (s + 1)(s + 2)(s + 3) Obtain the characteristic polynomial for the plant, with additional feedback gains, to design an observer. [3] Find the observer dominant poles, from which damping ratio, and natural frequency on can be obtained. You can use the following equations: 3= -In (OS%/100) √² + In² (OS%/100) TT T√√1-3² where OS is the overshoot and T, is the settling time. [7] Place the third pole 5 times as far from the imaginary axis as the dominant pole pair and find the desired characteristics equation. [2] Hence estimate the gain values for the observer design. [2] Wn = (a) (b) (c) Explain how the concepts of observability and observer are used in conjunction with control system design.
