Motor starting control method and device based on position sensorless control

The invention relates to a motor starting control method based on position sensorless control, and the method comprises the steps: starting a motor through employing a current closed-loop I/F control mode, a first d-axis target current # imgabs0 # being 0, and a first q-axis target current # imgabs1 # being equal to a motor current vector is0; and when the rotating speed of the motor meets a certain requirement, recording a working point (id0, iq0) of the last period of the current closed-loop I/F control mode, and switching from the current closed-loop I/F control mode to a field oriented control (FOC) mode, the initial value of the working point of the FOC mode is set to be the same as the working point (id0, iq0) of the last period of the current closed-loop I/F control mode. The invention further relates to a motor starting control device based on position sensorless control, a computer storage medium and the permanent magnet synchronous motor. 本申请涉及一种基于无位置传感器控制的电机启动控制方法，所述方法包括：采用电流闭环I/F控制模式来启动电机，其中第一d轴目标
