针对具有外部扰动的T-S模糊系统,利用分段模糊Lyapunov函数和线性矩阵不等式方法研究了模糊系统的镇定问题.给出了闭环系统渐近稳定的充分条件,提出了闭环系统γ一次优H∞控制器的参数化设计方法.仿真实例验证了所提出方法的有效性.
To with the disturbance nonlinear Takagi fuzzy system, based on piecewise fuzzy Lyapunov function and LMI method, the systematic design procedures are studied. The sufficient conditions for closed-loop system stability are derived. The parameters design method of γ-superior H∞ controller for closed-loop system is provided. Simulation results show the effectiveness of the proposed method.
