欧拉角表示法具有简便、几何意义明显等优点，同时姿态敏感器可以直接测出这些参数，能较方便地求解用这些姿态参数描述的姿态动力学方程。但采用欧拉角的姿态描述方法存在奇点问题，且需多次三角运算。而采用四元数表示方法则可以避免这些问题。(conversion between euler angle and quaternion method)

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)
