一类不确定非线性系统的鲁棒调节控制
Robust regulation control for a class of uncertain nonlinear systems
摘要
Abstract
The regulation control for the nonlinear uncertain systems is a central topic in robust control theory.This paper studies the robust regulation control problem for a class of nonlinear uncertain systems with unmodeled dynamics, uncertain nonlinearities, and unknown time-varying control coefficients.A robust regulation control scheme is presented using the changing supply rates technique,Nussbaum function gain as well as local small-gain conditions,and then the stability is analyzed.The simulation example verifies its efficacy.The results show that he proposed control scheme is robust against the unmodeled dynamics,uncertain nonlinearities,and unknown control coefficients;the changing supply rates technique could overcome the possible instability because of the unmodeled dynamic subsystem;Nussbaum function gain could effectively handle serious uncertainties in systems such as the unknown control direction,time-varying unknown control coefficients and so on;local small-gain conditions could well address the unmeasured states growth problems.关键词
