| 摘 要： | 研究表面贴装式永磁同步电机的弱磁控制策略,提出了一种修正电流设定值的方法.该方法由两部分组成:弱磁区域的确定和设定电流修正值的计算.电机运行所在的弱磁区域由恒转矩曲线方向和电流调节器输出电压递减方向之间的夹角来确定,输出电压的递减方向信息通过梯度下降法计算得到.设定电流修正值的大小根据该弱磁区域内转矩、电压变化量的方向...

| Abstract: | The flux weakening control strategy of SMPMSM is studied,a method of modifying the current setting is proposed.The method consists of two parts:one is the determination of the flux weakening region,another is the current setting modification.The flux weakening region is determined by the angle between the constant torque direction and the output of current regulator decreasing direction,the direction of voltage decreasing is calculated by using the gradient descent method.The current setting is modified by ... |
