针对表贴式永磁直线同步电机矢量控制系统参数设置需反复测量和调试的问题,提出一种自动整定的方法。测量电流控制器输出波形并计算相应的沃尔什一阶系数,反复迭代反电动势常数和定子电感,直至沃尔什一阶系数收敛到零,自动辨识表贴式永磁直线同步电机的电气参数；随后让电机自由运行辨识出机械参数；最后计算出速度和电流控制器的PI参数。样机测试结果验证了提出方法的有效性。

Directed against the problem of repetitious measurement and accommodation of the parameters of the vector control system of surfacemounted permanent magnet linear synchronous motor (SPMLSM), a method of automatic setting was proposed. By applying the linear velocity measurement current controller output waveform and calculating the corresponding Walsh coefficients of first order iteratively until the Walsh coefficients converge to zero, the electrical parameter of surfacemounted permanent magnet linear synchronous motor could be identified automatically and the mechanical parameters of the free running motor could be identified and finally the PI parameters of the speed controller and current controller could be calculated. The validity of the proposed method was verified by the prototype test results.
