基于跟踪误差调节的非线性自适应模糊预测控制

Nonlinear Adaptive Fuzzy Predictive Control Based on Tracking Error Adjustment

将模糊逻辑系统引入预测控制,对一类非线性离散系统提出了直接自适应模糊预测控制的方法.此方法首先建立被控对象的预测模型;然后基于此模型直接利用模糊逻辑系统设计预测控制器,并基于跟踪误差对控制器参数中的未知向量进行自适应调整;最后证明了此方法可使跟踪误差收敛到原点的一个小邻域内.

A direct adaptive fuzzy predictive control method for a class of nonlinear discrete systems is presented by introducing fuzzy logic system into predictive control strategy. The control plant is represented by a predictive model. A fuzzy logic system is used to design predictive controller directly. And the controller parameters are adjusted adaptively based on the tracking error. It is proved that the proposed method can make the tracking error converge to a small neighborhood of the origin.
