摘要
针对T -S模糊模型描述的非线性系统 ,提出一种基于线性矩阵不等式 (LMI)具有闭环极点约束的状态反馈H∞ 控制设计方法 ,将闭环系统稳定性和性能指标归结为线性矩阵不等式 (LMI)的凸规划问题 ,通过求解线性矩阵不等式得到满足要求的控制器参数。以倒立摆为例 ,对该方法进行了验证 ,结果表明该方法可行有效。
A design method for state feedback H ∞ control with robust ploe placem ent constraint is prposed in this paper. The method combines the stability condi tion of closed-loop T-S fuzzy systems and the reguired performanc e in a set of Linear matrix inequalities (LMIs), and the controller can be obtained by solving the LMIs.An example of the design for an inverted pendul um is given.
