一类非线性系统的动态补偿

Dynamic Compensation for a Class of Nonlinear Systems

本文考察一类非线性控制系统的调节问题。在一些常见的假设条件下,文中给出了动态补偿器的设计方法,这是一种基于状态观测器的补偿装置。结果表明:本文给出的动态补偿器的构造方法便于实际系统设计采用。

In this paper the regulation problem of a class of nonlinear control systems is studied. For this class of systems, the regulation by static state feedback is well known. But the effective design method to accomplish regulation by dynamic compensation with measurement output feedback has not been found yet when a state of system is not available directly. In this paper a design method for dynamic compensator is given under some conditions. The compensator is based on the state observer. The result shows that it will be convenient to use the method given in the paper in practical design of the system.
