Designing discrete time variable structure control with sliding mode (SM) schemes implies finding an asymptotically stable sliding surface with a control policy which assures the existence ... WebVariable structure control. Variable structure control ( VSC) is a form of discontinuous nonlinear control. The method alters the dynamics of a nonlinear system by application of a high-frequency switching control. The state - feedback control law is not a continuous function of time; it switches from one smooth condition to another.
