Fuzzy Control Technology for Drive System of Switched Reluctance Motor

A fuzzy self-correction controller based on DSP (TMS320LF240) micro-controller was designed to solve the problem that traditional controller can't meet the random disturbance parameters of reluctance motor having notable nonlinear. Parameters could be automatically adjusted and response is rapid. According to the demand that two windings provide electric power at the same time for switched reluctance motor (SR motor), the system adopted Mamdani model with two inputs, MAXMIN barycenter technique was used for judging manner. Fuzzy research table and driving software were designed. Experiment results with a 5.5KW SR motor illustrated that the four phases SRD with fuzzy control technology proposed in this paper has excellent driving character.
