针对一类多输入离散非线性系统给出了基于模糊双线性T-S模型的参数化新模型,用并行分布补偿算法(PDC)设计模糊控制器,以线性矩阵不等式(LM I)的形式给出系统H∞全局稳定的充分条件,并通过求解一系列线性矩阵不等式(LM I)给出控制器增益的设计方法,最后,通过仿真例子验证这个方法的有效性和可行性。
A new parametrization model based on fuzzy bilinear TS model is proposed for a class of multiple input discrete nonlinear systems. The fuzzy controller is designed by using parallel distributed compensation algorithm (PDC) and given as linear matrix inequality (LM I) The sufficient condition for the global stability of the system H∞ is given, and the design method of the gain of the controller is given by solving a series of linear matrix inequalities (LM I). Finally, the simulation results show the effectiveness and feasibility of the proposed method.
