N2 - In order to compensate for the effects of friction in IOC (Inter-satellite Optical Communication) coarse pointing subsystem of PAT(Pointing, Acquisition, Tracking) system, a PD controller is used to obtain a stable trajectory first, then wavelet neural network is used to approximate friction function on line to compensate for it. In addition, a robust term is used to eliminate the effects of approximation error of neural network and external disturbances. The system is proved to be stable and the parameters are proved to be bounded under the control scheme of this paper, using Lyapunov function methods. At last, simulation results show the validity of the control scheme.
