Fuzzy Logic Control For Switched Reluctance Variable Speed Linear Generator System

The paper introduces the developed switched reluctance variable speed linear generator system. The developed prototype is a type of three-phase switched reluctance linear generator system, which is made up of the three-phase 6/4 structure switched reluctance linear generator, the three-phase asymmetric bridge exciting power converter and the controller. The hardware of the prototype was introduced. The principles of the output power closed-loop control based on fuzzy logic were given. The input control parameters, the output control parameter and the fuzzy logic algorithm were described. The language parameter, the domain and the subordinate relationship of the deviation of the average output current, the deviation of the output voltage, and the increment of the duty ratio of the pulse width modulation signal were given. The prototype adopted the control strategy was tested experimentally. The measured output power and the measured phase current peak value were also given
