Research on approximate solution for nonlinear multi-variables harmonic control system

摘要

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 and the convergence of its solution is proved.
