Adaptive RBF Terminal Sliding Mode Applied in the Precision Real Time Tracking and Control System

It was necessary to keep precise pointing and tracking between two satellites to realize Rendezvous and Docking,laser communication as well as counterwork.An adaptive RBF terminal sliding mode control was proposed in the coarse tracking subsystem of the Acquisition,Tracking and Pointing (ATP) system.ATerminal sliding mode controller was usedto obtain a stable and fast tracking first,then the upper bound of system uncertainties were estimated through an adaptive RBF neural network.The system was proved to be stable and the parameters are provedto be bounded under the control scheme of this paper,using Lyapunov methodology.At last,simulation results show the highly robust and efficient controller design.
