WebFeb 28, 2024 · Poles and Zeros of a transfer function are the frequencies for which the value of the denominator and numerator of transfer function becomes infinite and zero respectively. The values of the poles and the zeros of a system determine whether the system is stable, and how well the system performs. WebMar 5, 2024 · The closed-loop characteristic polynomial for a unity-gain feedback control system is: Δ(s) = (s + 1)(s + 2) + K(2 − s). Using the ITAE index, a desired second-order polynomial is selected as: Δdes(s) = s2 + 1.4ωns + ω2 n. By comparing the polynomial coefficients, we obtain two equations that are solved to obtain: ωn = 1.76rad s and K = 0.54. nature trails park normandy park https://pcdotgaming.com
