Abstract :
Based on fuzzy logic, a method of integral sliding mode variable structure control is presented, which is applied to a class of linear system in the presence of disturbances and model uncertainties. This method is formed by combing sliding mode variable structure control with fuzzy control, furthermore an integral control is introduced into it in order to eliminate steady-state error and improve control precision. Simulation results show that the control system not only exhibits strong robustness, excellent tracking characteristics and controlling effects, but also avoids the chattering phenomenon
