摘要

The control of second order system with uncertain parameters and single unknown control coefficient is researched. And a kind of adaptive strategy is hybrid. With sliding mode method, and the adaptive strategy is used to cope with uncertain parameters produced in the process of sliding mode controller design. At last, detailed numerical simulation is done to testify the rightness of the proposed method and also multi-time random simulations are done to testify the robustness of the controller. And the main conclusion is that the sliding mode control has very good consistency since the strategy formation is almost the same as the controller for system with known control coefficient, and high gain is necessary for system with single uncertain control coefficient.
