摘要
本文讨论一类非线性系统的全局鲁棒输出调节问题.假定被控非线性系统的系统输入方向未知,且产生参考或扰动信号的外部系统含未知参数,这为控制律的设计带来了挑战.文章使用自适应控制方法和内模原理,解决了一类相对阶为1的非线性输出反馈系统的输出调节问题,并将结果应用于处理Lorenz系统的渐近跟踪问题.
We study the global robust output regulation problem for a class of nonlinear output feedback systems.In this problem,it is assumed that the exosystem and the control direction are unknown,which poses challenges in control law design.Adaptive control scheme and internal model principle are employed to solve the output regulation problem for nonlinear output feedback systems with relative degree 1.The controller proposed in this paper is also applied to solving an asymptotic tracking problem of the controlled Lorenz system.
