Abstract: The approach of experimental uniform design in statistics is used in the optimal design of parameters. The basic principle of uniform design and its application in the optimal design of the quantifying factors and the scale factor of a fuzzy controller are introduced. Compared with the genetic optimal algorithm and the approach of orthogonal design, the approach of uniform design can greatly reduce the required times of experiment and the computation time. Simulations show the availability and the effectiveness of the present approach.

Key words: fuzzy contr ol, par ameter optimization, uniform design, exper iment design
