摘要：

Traditional PI regulator has some defects. Direct torque control (DTC) for permanent magnet synchronous motor (PMSM) based on active-disturbance rejection control (ADRC) optimized by least squares support vector machines (LSSVM) method was proposed in this paper. The speed regulator based on ADRC was designed with the inputs of given speed and real speed and the output of given electromagnet torque. The Gaussian radial basis kernel function was chosen in the model. The realization of the LSSVM regression model embedded in ADRC regulator was analyzed in-depth and detailed, which optimized the ADRC regulator. The ADRC observation precision and dynamic response are improved. The effect of motor parameters and load disturbances on the system is significantly reduced. The anti-interference ability of the system is further improved. Simulation and experiment results have verified the feasibility and effectiveness of this method. © 2014 Chin. Soc. for Elec. Eng.
