一类非线性不确定系统的鲁棒H_∞控制

ROBUST H ∞ CONTROL FOR NONLINEAR SYSTEMS WITHPARAMETER UNCERTAINTY

利用Ｈａｍｉｌｔｏｎ－Ｊａｃｏｂｉ不等式讨论了一类含不确定项的非线性控制系统的鲁棒Ｈ∞控制问题，分别得到了状态反馈控制器和动态输出反馈控制器，使得相应的闭环系统具有鲁棒Ｈ∞特性的充分条件，并且给出了它们的具体设计．

In this paper, we study the problem of robust H ∞ control design for a class of nonlinear systems with parameter uncertainty by means of Hamilton Jacobi inequality. We obtain the sufficient conditions for the existence of static state feedback controller and dynamic output feedback controller under which the closed loop systems have robust H ∞ performance, respectively. Furthermore, we develop the design for robust controllers.
