时频分析中的Wigner-Ville方法函数(Time-frequency analysis of the Wigner-Ville method function)

说明：  这是Maple下使用的“吴方法”推理求解多项式方程组的源代码。(use of the "Wu's Method" reasoning to solve polynomial equations source.)

PGPI(NUM,DEN,W,FI,A) plots the stability boundary locus L(KP,KI,W)in the (KP,KI)-plane for an LTI system with transfer function defined by its NUM, DEN coefficients and driven by a PI controller with transfer function, C(s)=kp+(ki/s). Frequency (W) gridding becomes important. Phase Margin, FI, and Gain Margin, A, can be defined. The method works for open loop stable or unstable, minimum or nonminimum phase systems. With Examples. Method and examples used are form "Computation of Stabilizing PI and PID Controllers" by Nusret Tan, Ibrahim Kaya and Dereck P. Atherton. MATLAB release MATLAB 7.5 (R2007b)
