- Q4. a) A purely derivative controller (i.e. with a zero at the origin only) is defined by an improper transfer function. Considering its asymptotic behaviour, explain why a purely derivative controller is difficult to implement in practice. Relate your explanation to the potential limitations on system performance. b) Discuss the potential issues faced by a control system with a large cut-off frequency. Relate your discussion to the implications on system performance. c) The transfer function of a lag compensator is given by 2 KPID(S) = 2.2++0.2s S By using the asymptotic approximation technique: (i) Obtain the standard form and corner frequency for each individual component of KPID(S). (ii) Clearly describe the asymptotic behaviour of each individual component of KPID(S).arrow_forwardModule Code: EN2058 Q1. a) List the advantages and disadvantages of a closed loop system compared to an open loop system. b) c) What is the procedure for designing a control system for a bread toaster? An RC circuit is given in Figure Q1. vi(t) and v(t) are the input and output voltages. (i) Derive the transfer function of the circuit.

Sketching is not needed.arrow_forwardQ3. a) The frequency response method enables the study of the steady-state response of a system G(s). What type of inputs are used for frequency response? If the system is linear and stable, how does the output differ from the input? Compare the main characteristics of two types frequency response plots. b) Consider the control system shown in Figure Q3.

(i) Considering definitions in the study of bounded-input bounded-output stability, is G(s) stable? Classify the poles and zeros of G(s). (ii) G(s) defined in Figure Q3 is a system completely characterised by its transfer function. Explain why this is the case.
