7Conclusions

1)A new intelligent anti-swing control scheme is proposed with combination of SMC’s robustness and FNN’s independence on system model。 The bridge crane is simplified into three multi-input subsystems, four sliding mode surfaces are defined and fuzzy neural networks sliding controller is designed。 It is capable of tackling non-linear system with parameter uncertainties。

2)Compared with conventional sliding mode control, the system achieves good positioning accuracy and significant sway reduction with considering changes of lifting-rope when the bridge crane system model has uncertainties and disturbance。

3)Moreover, by the PSO algorithm, the parameters of controller are optimized to accelerate system convergence, the inherent chattering phenomena of sliding mode control can be eliminated and the performances of control system can be ameliorated。 The simulation results show that the correctness and validity of this method。
