PID控制线性时滞反馈系统的稳定性

Stability of PID-Controlled Linear Time-Delay Feedback Systems

Gianpasquale Martelli

摘要:

由线性时滞对象和PID控制器组成的反馈系统的稳定性研究已有多年,其中Nyquist判据、Hermite-Biehler定理的推广和根定位法是著名的。这些研究的主要目的是确定允许稳定的控制器参数的范围。这些区域的边界的明确和完整的表达式和有限步数的计算程序,现在只适用于一阶植物,提供一个时间延迟。本文在庞特里亚金研究的基础上,对任意阶对象给出了同样的结果。

英文摘要:

The stability of feedback systems consisting of linear time-delay plants and PID controllers has been investigated for many years by means of several methods, of which the Nyquist criterion, a generalization of the Hermite-Biehler Theorem, and the root location method are well known. The main purpose of these researches is to determine the range of controller parameters that allow stability. Explicit and complete expressions of the boundaries of these regions and computation procedures with a finite number of steps are now available only for first-order plants, provided with one time delay. In this note, the same results, based on Pontryagin's studies, are presented for arbitrary-order plants.
