Abstract:
According to hypersonic flight vehicle of highly nonlinear and strong coupling characteristics, sliding mode variable structure control based on RBF neural network regulating parameters was proposed. Sliding mode variable structure controller makes the hypersonic flight vehicle stably fly,but when the sys-tem states arrived at the sliding mode surface,it will emerge severe chattering,which would influence en-gineering applications. RBF neural networks can approximate nonlinear functions in arbitrary precision un-der certain conditions,in addition it has capacity of strong self-learning,adaptive and self-organizing. The controller that together RBF neural network with sliding mode variable structure can eliminate chattering problem generated by sliding mode variable structure control to a certain extent. Simulation was conducted by giving altitude and velocity command on the cruise condition of hypersonic flight vehicles. Simulation results show that RBF neural network based sliding mode variable structure controller designed here en-sures rapidity,robustness and immunity of the hypersonic flight vehicle,while overcoming the problems of
actuator chattering.
