Unformatted text preview: ω g . c) Determine the resonant-peak M pω , the resonant frequency ω r and the bandwidth ω B . d) Determine the percent-overshoot PO of the unit-step response and the approximate settling time t s . e) Now suppose that there is a delay in the system, i.e.,that G ( s ) is multiplied by the delay transfer-function e-sT d . What is the maximum time-delay T d that your system can tolerate such that the closed-loop system is still stable? The design for part (ii) can be the simplest design that satisﬁes the criteria. You can use MATLAB as a design aid, to compute, to obtain details of plots and to verify your design. All plots and sketches should be hand-sketched, but you can verify them using MATLAB.
