摘要
根据基于模型的模糊控制策略 ,提出一种薄板系统振动主动控制器的设计 .与传统的方法不同之处在于作者首先采用递归的RAMAX算法和PEM进行模糊参数识别 ,从而建模 ;其次 ,通过在线调整系数矩阵Θ(α)的元素和目标函数优化 ,进行自适应控制器合成 .数值仿真和实验结果验证了本文所提方法的有效性和鲁棒性 .
By means of the model based fuzzy control strategy, an active controller for vibration control of thin plate systems is designed. Firstly, the fuzzy modelling is carried out. Different from the conventional parameter identification methods, the parameter l is identified using the recursive ARMAX approach with PEM. Then, an adaptive controller is synthesized by adjusting the elements of the coefficient matrix Θ(α) on line and objective function optimization. Experiments are carried out. The numerical simulation and experimental results verify the effectiveness and robustness of the presented method.
