PID controller: KG (5) - K(s’+1.55 +0.5) Plant: G (s)=- 1 (20s +1)(10s +1)(0.5s +1) For this control system, do the following tasks. Advice: Before you start, it is advised that you convert G,(s) to a standard form so that the leading coefficients of the denominator polynomials become 1 (without altering the overall transfer function). (1) Plot the root locus for 0 <K<using a computer tool, e.g., Matlab tools such as rlocus(), rltool() or any appropriate computer tools. Also, read...
