A Hybrid Intelligent Controller Based on "Consultation of Doctors"

Abstract How to effectively integrate different intelligent controllers has become an interesting issue in the field of intelligent control. In this paper, a framework of a hybrid intelligent control system is presented, in which multiple different controllers are effectively integrated together and to gain better control quality, working on the principle of “the consultation of doctors᾿. An on-line approach analogous to human debating and compromising is adopted to coordinate different controllers to overcome their respective shortcomings by learning the other’s strong points via a coordinator. Performance evaluation is made based on the hybrid controller consisting of an expert controller and a neurocontroller. Knowledge transference and sharing between the expert controller and the neurocontroller is achieved by making use of a mapping between the usable-characteristic vector space and the output vector space. Simulation shows that this approach provides good control quality and high reliability.
