非线性系统的多模型预测函数控制方法的研究

Research of Multiple Model Predictive Functional Control Method about Nonlinear Systems

针对实际系统存在非线性、时变性、不确定性和多工况的特点,采用传统预测函数控制理论和方法难以取得满意的控制效果,本文提出了基于预测函数控制的多模型控制方法,对每个模型建立局部控制器,由各局部控制器的加权和构成被控对象的控制器。仿真结果表明,采用多模型预测函数控制策略的控制系统的动态品质明显优于单一模型控制。

The actual system for non-linear,time-varying,uncertainties and many of the characteristics of working conditions,using the traditional predictive functional control theory and method of control difficult to obtain satisfactory results,this paper,predictive functional control based on multi-model control method,each model set up the local controller,local controller has a weighting and composition of the object controller. The simulation results show that the use of multi-model predictive functional control strategy of dynamic quality control system is superior to a single model control.
