Research on Approximate Solution for Nonlinear Multi-variables Harmonic Control System

对于一类非线性多变量控制系统,当要求各被控制变量满足任意函数的协调关系,被控制对象为时变非线性系统的情况下,给出了"非线性多变量协调控制原则",以及相应的非线性协调偏差状态方程,并给出了该方程的任意阶近似解的求解方法。

To a nonlinear multi-variables control system with time-varying controlled objects and harmonic relationship of arbitrary function among controlled variables, ＂the rules of harmonic control for nonlinear multi-variables systems＂ are given, the state equation for harmonic error of nonlinear system is gained, its any order approximate solution is given.
