一类时变非线性系统自适应控制

Adaptive Control of Non-Linear Systems with a Time-Varying Structure

针对非线性时变系统提出一种间接自适应方法。利用时尺变量函数,将非线性系统划分为若干子系统,间接自适应方法对任意信号都具有稳定性。仿真结果表明了,此法的有效性。

In this paper an indirect adaptive control method is presented for a class of non-linear systems with a time-varying structure. The non-linear systems are divided into a finite number of sub-systems, which are interpolated by functions of an exogenous scheduling variable. The indirect adaptive method yields stability of all signals in the closed-loop. The results of simulation show the method is effective.
