Abstract
To reduce the difficulties in choosing an appropriate fuzzy knowledge base, ie., scaling factors, membership functions and rules etc., of a fuzzy controller, a hierarchical fuzzy controller (HFC) is proposed. This hierarchical fuzzy controller is divided into several hierarchical level subcontrollers, which can be designed separately. Each subcontroller can be designed easily and can perform well at a certain level and running state. According to the hierarchical structure, when all the subcontrollers perform well, the hierarchical fuzzy controller can gain good performance.
