【Abstract】 A variable structure controller is designed for linear singular systems with uncertainties.And a sufficient condition is obtained for stable sliding mode dynamics by using linear matrix inequality(LMI) approach.The variable structure controller guarantees the trajectory of the system state can reach the sliding surface in finite time and stay on it forever.The sliding mode dynamics is regular,impulse-free and asymptotically stable.更多还原
