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_forward
