摘要
针对具有参数不确定性的机器人动力学系统,根据滑模控制原理并利用模糊系统的逼近能力,提出了一种自适应模糊滑模控制方案.控制结构中采用模糊系统去自适应补偿过程的不确定性.利用Lyapunov定理证明了闭环模糊控制系统的稳定性和跟踪误差的收敛性.仿真结果表明了所提控制策略的有效性.
Based on sliding-mode control theory and the approximation capability of fuzzy systems, a new scheme of adaptive fuzzy sliding-mode control system is proposed for robot manipulators with uncertainties. The control architecture employs fuzzy systems to compensate adaptively for plant uncertainties. The stability of the fuzzy control system and the convergence of the tracking errors are ensured by using the Lyapunov theory. The simulation result verifies the validity of the control scheme.
