Based on the status of sliding mode control(SMC) and the new requirements from the practice for the theory of SMC, some ways are put forward to resolve the problems existed in SMC, also the corresponding results are given. First, four controllers of fuzzy sliding mode control are proposed by absorbed the fuzzy control theory basis on SMC, which is proved that the designed controller is effective by numerical examples. Second, two designed ways of adaptive fuzzy sliding mode control that are proposed are better, it is proved by the invert pendulum which is typical nonlinear system. Finally, A decentralized Parallel distributed compensation controller with SMC guarantees that the closed-loop fuzzy large-scale system is stability, which is based on the theory of Lyapunov,decentralized control and SMC. |
