【Abstract】 A method was presented to design robust sliding mode plane in the presence of mismatched uncertainties based on quadratic stability. The sliding mode control was derived according to the reaching condition. It enabled uncertain system to reach sliding mode plane within finite time to guarantee the global stability of the system. Simulation results showed the validity of the proposed method.更多还原
