摘要
针对一类由非线性增益函数与典型 PID控制器级联组成的非线性系统 ,采用波波夫判据对此类闭环控制系统进行稳定性分析。分别确定了确保非线性 PID,P,PI,PD闭环控制系统稳定的非线性增益的有效取值范围 。
The stability of a nonlinear control system which consists of a sector bounded nonlinear gain in cascade with a fixed linear PID controller is analyzed using Popov stability criterion. The relationship between the parameters and the stability is derived, and the criterion to determine the nonlinear gain is presented, which lays a solid base for the engineering design of this kind of PID controller.
