摘要
研究了含不确定外动态的仿射非线性系统的鲁棒反馈控制问题.基于相对阶和零动态的概念,利用反馈线性化的方法和系统状态的线性变换,得到状态反馈控制律.当反馈控制律作用于该系统时,闭环系统是指数稳定的.
This paper deals with the problem of the robust feedback control of atone nonlinear systems with uncertain exogenous dynamics. Based on the concepts of relative degree and zero dynamics, the state feedback controllers are obtained by using feedback linearization and linear transformations of the states. When the feedback control laws are applied to a system, the system is exponential stable.
