Abstract: The traditional motor system problems brake low recovery efficiency of regenerative braking sys-tem, and accordingly put forward based on the fuzzy mathematics method of permanent magnet motor rege-nerative braking system based on fuzzy mathematics observation of stator flux, the amplitude of the stator flux linkage control parameters, and then ｓｅｌｅｃｔ the zero vector and non-zero transient slip loss to adjust and control the output torque constant, guarantee the output current harmonic, smooth operation, and on the basis of the structure of regenerative braking control, to achieve the permanent magnet motor regenerative braking system of fuzzy mathematics. Finally, the numerical values of each parameter are input into the ADVISOR, and the simulation experiment is conducted with the ADVISOR software. The experimental results prove that the method is highly effective and practical, and fully meets the research requirements.
