摘　　要：研究一类不确定非线性系统模糊鲁棒跟踪控制的设计.基于存在外界干扰的不确定非线性系统的T-S模糊模型,考察被控系统跟踪参考信号的误差,得出跟踪误差指数稳定的约束条件,在跟踪控制与镇定控制一致的前提下研究了H∞模糊鲁棒跟踪控制器的设计问题,基于Matlab的LMI和FLC工具可实现对此问题求解.仿真实例验证了算法的有效性.This paper deals with the design problem of fuzzy robust tracking control for a class of uncertain nonlinear systems. The uncertain nonlinear systems descriptor based on T-S fuzzy model with external disturbance was considered, the tracking error of the controlled system following the reference signal was studied, and the constraint conditions of the tracking error＇ s exponential stability were obtained. Under the coherence of tracking control and stabilization control, the design techniques of H∞ fuzzy robust tracking controller were studied, which can be solved by using LMI and FLC tools of Matlab. The simulation results demonstrate the effectivity of the proposed method.
