摘　　要：针对采用无位置传感器控制的永磁同步电机,零低速下位置估计精度较低,导致应用于航空起动时重载起动失败,提出了一种基于高频复合信号注入的无位置传感器控制方法。基于电机本身固有的电感饱和效应以及内置式电机的凸极效应,在电机中注入高频复合电压信号。准确估计出电机初始位置的同时,对初始磁极进行有效辨识,准确估算出电机实际位置,实现内置式航空起动电机的无位置传感器重载起动控制。实验结果表明,所提方法能够有效且准确估计电机转子位置,同时能够应用于实际电机的满负载起动工况,实现了航空起动电机的重载起动。The position sensorless control method of permanent magnet synchronous motor(PMSM)has some problems such as low position estimation accuracy at zero-low speeds,which leads to failure in heavy-load starting applications in aviation.To overcome this challenge,aposition sensorless control method based on high-frequency composite signal injection was introduced.This method exploited the inherent inductance saturation effect of the motor and the salient-pole effect of interior motors.By injecting a high-frequency composite voltage signal into the motor,it not only estimated the initial position of the motor accurately but also identified the initial magnetic the initial magnetic poleeffectively,enabling precise estimation of the motor’s actual position.As a result,sensorlessheavy-load starting control for interior aviation starter motors was achieved.Experimental results demonstrate that the proposed method can estimate rotor position effectively and accurately,and it can be applied to full-load starting conditions of actual motors,realizing heavy-load starting for aviation starter motors.
