【Abstract】 As the Switched Reluctance Motor (SRM) possesses highly nonlinear property due to its special structure and the Switched Reluctance Motor Drive(SRD)appears as a multi\|variable coupling system with serious nonlinearity, the perfect control can not be obtained by the ordinary control methods. To validate the effectiveness of the self\|adapting fuzzy control on a SRD system, a SRM mathematic model was established on the base of the nonlinear inductance model, and the self\|adapting fuzzy control strategy was applied to the system in this paper. Simulation and experiment study demonstrated that this sort of control is able to ensure the SRD to achieve both better static and dynamic performances.更多还原
