Motor rotation speed control parameter optimization method and system based on improved SPSA

The invention relates to a motor rotation speed control parameter optimization method and system based on improved SPSA. The method comprises the following steps of S1, initialization, S2, an optimization process during which a new, to-be-experimented and calibrated iterative control parameter combination is given according to the improved SPSA method, S3, a preprocessing process during which thecalibrated iterative control parameter combination is preprocessed to a practical feasible iterative control parameter combination, S4, an experiment test process, S6, a post processing process duringwhich according to a formula as described in the specifications, the ITAE index is calculated to evaluate the control performance of the motor and the practical feasible iterative control parameter combination is calibrated, and S6, an evaluation process during which real-time evaluation is carried out on whether the practical feasible iterative control parameter combination meets optimality according to the practical fea
