针对传统PI调节器的缺陷，提出一种基于最小二乘支持向量机(least squares support vector machine，LSSVM)优化自抗扰控制器(active-disturbance rejection control， ADRC)的永磁同步电机直接转矩控制方法。以给定转速和实际转速作为输入信号，以给定电磁转矩作为输出信号，设计了 ADRC 速度调节器；在此基础上，在回归模型中选取高斯径向基核函数，深入分析了将LSSVM回归模型有效嵌入ADRC调节器的实现方法，实现对ADRC控制器的优化，以提高 ADRC 观测精度及系统动态响应速度，很大程度上降低了电机参数变化和负载扰动对系统的影响，进一步改善了系统的抗干扰能力。仿真和实验结果验证了该方法的可行性和有效性。

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.
