摘要

In this paper, a robust adaptive PID-type controller incorporating a fuzzy logic system and a sliding-mode control action for robust Hinfin tracking performance is developed in spacecraft attitude maneuvers under parameter uncertainties and external disturbances. The fuzzy logic system is used to compensate the parameter uncertainties. The robust adaptive PID-type tracking control problems are characterized in terms of eigenvalue problem (EVP). The EVP can be efficiently solved by the LMI toolbox in Matlab. The proposed methods are simple and the PID parameters can be obtained systematically. Simulation results indicate that the desired performance for the tracking control schemes of the uncertain spacecraft systems can be achieved using the proposed methods
