Recently fuzzy logic has been utilized for non-linear controls, and many research studies on design methods have also been reported. The design method based on fuzzy models of controlled objects is effective in reducing the amount of labor in control knowledge acquisition, and also enables to design to design controllers for controlled objects without control experts. However, no study on design method of fuzzy controllers, which utilizes the feature of fuzzy controls in that control rules are easy to understand, and considers required responses of control systems, has been reproted.This paper presents an automatic design method of fuzzy controllers using the "Rule-to-Rule Mapping" method for describing the dynamical behavior of fuzzy control systems. The fuzzy controller is designed based on both linguistic specifications translated from required responses of the control system and the fuzzy model of the controlled object. The feasibility of the method is examined by experiments with an inverted pendulum. The results show that the method is effective to satisfy the linguistic requirements.
