摘要
针对一类非线性对象提出了基于Wiener模型的非线性系统自适应预测函数控制方法。利用带遗忘因子的递推最小二乘算法在线辨识得到Wiener模型核参数,根据所得模型参数直接计算得到非线性预测函数控制律,而且使控制律计算容易,适用于具有一定非线性的被控对象,并能适应被控对象的环境变化。
A new strategy of adaptive predictive function control based Wiener model for nonlinear system is developed. The parameters of Wiener model are identified by the recursive least square method with forgetting factor. Based on the identified result, The Adaptive Predictive Function Controller (PFC) is designed. The result of simulation illustrates performance of the derived control strategy for nonlinear time-varying system.
