Abstract:The process of complex uncertainty is difficult to describe by mathematical model. In order to avoid the predicament of mathematical paradigm modeling and control in complex uncertainty process control, this paper explored a kind of model based intelligent control strategy. In this paper, based on the principle of decomposition coordination, it made the anatomy on the difficulties in process control, summarized up the cybernetics characteristic of the complex uncertainty process in bottom layer, studied on the intelligent control strategy of model free multimodal faced to independent subprocess, and constructed a sort of multimodal control algorithm. The response curves of simulation result demonstrated that the multimodal control strategy based on human simulated intelligent control can obtain the expected good control quality. The research results show that the free multimodal control strategy proposed in this paper is reasonable and feasible.
