Adaptive Fuzzy Predictive Control of Satellite Attitude Based on Hierarchical Fuzzy Systems

Based on the hierarchical fuzzy systems (HFS), the tracking control of satellite attitude with uncertain dynamical models is investigated, and a direct adaptive fuzzy predictive control method is presented. First, a nonlinear generalized predictive control (NGPC) law is designed based on the satellite attitude dynamical model, then, a controller are constructed by using HFS to approximate model uncertainties, respectively. It is proved that satellite can track the desired attitude trajectory and the tracking error converges to a small neighborhood of the origin by the use of the designed controller. Simulation results show the effectiveness of the proposed method.
