Automatic design of fuzzy controllers

In this note, we propose to use adaptive fuzzy controller as a mean to gene rate the rule base of fuzzy controller automatically. Specifically, we run an adaptive fuzzy controller from a number of initial conditions such that the trajectories of these runs cover the domain of interest. Since the adap tive fuzzy controller can automatically generate control parameters along t he trajectories, we store these parameters after each run. The final fuzzy rule base is constructed from these stored parameters. Since the trajectori es cover the whole domain, the rule base generated is complete. The main ad vantage of the method is that a complete fuzzy rule base can be generated a utomatically without domain experts and without mathematical model. (C) 199 9 Elsevier Science Ltd.
