Sliding mode variable structure control
Sliding mode variable structure control
Sliding mode variable structure control
Sliding mode variable structure control is a nonlinear control method. His basic thoughts is to use a switch of discontinuous control strategy to force the state variables of the system on the sliding of a designed surface movement. Advantages of sliding mode variable structure control is not sensitive to system parameter variations and external disturbances, robustness. However, the inverter power supply system, to determine an ideal sliding surface is very difficult. And, in the digital method to achieve this control mode, the switching frequency must be high enough.
