| titleOfInvention | Position sensing method of brushless DC motor based on LSSVM hierarchical classification |
| abstract | Aiming at the problem of rotor position detection of the brushless DC motor, the invention proposes a position sensing method of the brushless DC motor based on the least squares support vector machine (LSSVM) hierarchical classification. The method proposed by the present invention takes the stator voltage and current of the brushless DC motor as the input of the decision-making LSSVM, and the rotor position information as the output, divides the DC motor rotor position into 6 regions, and each LSSVM outputs the combination of the corresponding region class, and gradually divides it into six regions. Layer decision-making until the corresponding area of the rotor is distinguished; the LSSVM network is trained by the grid optimization method to determine the optimal parameters of the LSSVM, and then the trained network model is applied to the motor operation, and the motor stator voltage and current are collected as the input of the LSSVM , the final rotor position information is determined through hierarchical decision-making, and the logical commutation signal is calculated by the rotor position to determine the on-off of the corresponding switch tube corresponding to each area, that is, the commutation logic signal. |
