Abstract:
Aimed at the problems of flexible-link flexible-joint space manipulator with parameter uncertainties and external disturbances to track the desired motion, the T-S fuzzy control and double-flexible vibration parallel control were proposed. Firstly, a joint flexibility compensation controller was introduced to improve the equivalent stiffness of each joint. Secondly, the error dynamic equations were obtained based on feedback linearization in the trajectory tracking procedure, and control parameters of fuzzy control was selected by Lyapunov stability theory.Subsequently, the fuzzy sliding mode control was improved with simple T-S fuzzy rules. The great advantage of proposed control is free of undesirable chattering phenomenon in sliding mode control and light burden of computations. Then, the double-flexible parallel control was presented to suppress the vibration of flexible links. Finally, the simulation results on a space manipulator demonstrate the validity of the proposed control scheme. © 2016, China Mechanical Engineering Magazine Office. All right reserved.
