| 摘 要： | 针对一类模有界的参数不确定Takagi-Sugeno(T-S)模糊系统,在分析模糊系统前提规则结构的基础上,设计了一种新的并行分配补偿(PDC)控制器,研究了其鲁棒控制问题。基于分段Lyapunov稳定性理论,导出了线性矩阵不等式(LMI)形式的鲁棒控制器设计方法。该方法充分利用了模糊系统隶属度函数的结构信息,降低了采用线性矩阵不等式方法求解的难度。仿真实验证明,通过该方法设计的模糊控制系统,具有良好的鲁棒性能,控制效果良好。

| Abstract: | The robust control problem for a class of uncertain Takagi-Sugeno(T-S) fuzzy systems is dealt with.A new parallel distributed compensation(PDC) scheme is presented for the T-S fuzzy systems with parametric uncertainties by analyzing the structure of premise rule base.Based on the piecewise Lyapunov stability theory,a sufficient condition is derived for robust stabilization of the fuzzy systems in the form of linear matrix inequalities(LMIs).This method fully utilizes the structure information of the fuzzy systems and the difficulty of solving LMIs is reduced.The simulation result shows that the robust control system adopting the designed method has good performance and robust capability. |
