摘要: 研究一类带不确定输入动态非线性系统的H∞控制问题.在输入动态存在的条件下, 利用反传设计方法构造了鲁棒状态反馈控制器,使得闭环系统在零初始状态下从干扰到输出的 L2增益任意小,同时在干扰输入恒为零时闭环系统是全局渐近稳定的.Abstract: The problem of robust H∞. control of a class of nonlinear systems with input dynamical uncertainty is dealt with. By the recursive design approach, a robust controller is constructed such that the closed-loop system has an arbitrarily small L2 gain from disturbance to output and in the absence of disturbance, the closed-loop system is globally asymptotically stable.
