复杂系统的多内模控制策略

针对实际对象在不同工况下的模型参数变化或突变，提出了基于多模型切换的内横控制方法，并对系统的稳定性给出了证明。在着干不同的工况点采用不同的模型，并设计出相应的控制器，根据运行工况选择相应的控制器，从而实现全工况运行的自适应控制。仿真结果表明。该控制策略比常规的单内模控制在大范围具有更好的控制品质。

Multiple internal model control strategy of complicated systems

In order to cope with changes or sudden changes in the time parameter of models of real processes under different circumst ances, internal model control based on multiple models is presented. Stability of the system is proved. According to the operating conditio ns over which the control system is expected to operate, a set of linear models is developed and the controller associated with each model is designed. By means of choosing a appropriate controller at the different load operating scope, the controller can satisfy the control performance specifications over the entire operating conditions of the plant. Simulations show that the method is superior to the conventional single intemal model control in performance.
