The estimation procedure is based on the steady - state characteristics versus slip curves . the sum of squares of differences between calculated and experimental characteristics is employed as the fitting criterion . the machine parameters are obtained by minimizing the least - squares cost function using genetic algorithms 该方法利用电机稳态特性曲线，以特性计算值和实验值的拟合误差的平方和作为判断准则，通过应用遗传算法最小化二乘准则函数来获取电机参数。
