【Abstract】 A class of robust control design with states of nonlinear uncertainty is investigated. Based on the standard H ∞ control state with feedback, and for all unknown bounded uncertainty, the design methods for such kind of uncertainty problems are given. The parameterized description of the controller is also obtained. For NC servo control system of bounded non linear perturbation, an appropriate controller is designed so as to give the system a better robustness and to guarantee a sufficient precision.更多还原
