Abstract: In view of the nonlinear characteristic of switched reluctance motors,a fuzzy PID control method based on adaptive universe technology was proposed.With the adaptive universe theory,the universe-adaptive fuzzy PID controller was designed accordingly.The model of switched reluctance motor and the controller were built on the Matlab.Under the two control methods, universe-adaptive fuzzy PID and traditional PID,the performances of the switched reluctance motor were contrasted. Results of the experiment prove that,compared with the traditional PID controller,the universe-adaptive fuzzy PID controller responds faster, pessesses higher control precision and functions better in terms of anti-jamming. Key words: adaptive universe; fuzzy PID control; switched reluctance motors |
