这篇文章提供为部分顺序的时间延期系统调节 PI 控制器的方法的一个图形的参数。首先，在比例积分的飞机的 PI 控制器的完全的稳定区域一修理，以对部分延期的系统适用的一个图形的稳定性标准被决定。然后，稳定的区域是关于参数的最大化的经分解期望靠近环的系统的最各种各样的行为。最后由相对获得和阶段边缘的要求定义适当函数，在最大化的稳定的区域的曲线令人满意预先指定的获得和阶段边缘被拉，它释放调节过程的一个灵活参数。数字例子被给说明设计步。

英文摘要：

This article provides a graphical parameter tuning method of PI^λ controllers for fractional-order time-delay systems. First, the complete stabilizing region of PI^λ controller in proportional-integral plane, for a fixed A, is determined in terms of a graphical stability criterion applicable to fractional-delay systems. Then, the stabilizing region is maximized analytically with respect to parameter ）, to expect the most various behaviors of the closed-loop systems. Finally, by defining appropriate functions relative to the requirements of gain and phase margins, the curves in the maximized stabilizing region satisfying the pre-specified gain and phase margins are drawn, which releases a flexible parameter tuning procedure. Numerical examples are given to illustrate the design steps.
