The invention relates to a multi-target optimization control method of a switched reluctance machine. The multi-target optimization control method comprises the steps of (1) determining three excitation parameter optimization targets of an output power, working efficiency and a torque smooth coefficient; (2) defining a single-target optimization function, determining respective ranges of an excitation parameter opening angle, a turn-off angle, a reference current and a motor rotational speed, and respectively calculating values of the output power, the working efficiency and the torque smoothcoefficient within the ranges; (3) changing a combination of the opening angle and the turn-off angle until maximum values of the three excitation parameter optimization targets of the output power, the working efficiency and the torque smooth coefficient are respectively obtained; and (4) using the maximum value of an excitation parameter optimization model in a multi-target function, and matching different weight coefficients to obtain a multi-target optimization function optimal value model. By the multi-target optimization control method, the stable combination of the opening angle and theturn-off angle can be obtained within a certain rotational speed range, the output power and the working efficiency of the switched reluctance machine are improved, and meanwhile, the torque pulse ofthe switched reluctance machine is also reduced.
