摘要
本文针对非线性控制系统讨沦其鲁棒性问题,并提出非线性系统的鲁棒性指标.当该非线性系统本身或其控制律受到可加式扰动时,只要该扰动函数满足扇形约束条件,则该非线性系统为鲁棒性稳定.该扇形中的参数即由本文中提出的鲁棒性指标所决定.
In this paper we discuss the robustness of a general system with additive perturbation which includes parame-ter perturbation and perturbed control action.The gain margin for robust stability will be given.We show that thegain margin,defined as robustness degree,is a sufficient condition for the robust stability of a system with cer-tain perturbations.
