摘要:
针对以往电机低速运行时转子位置检测不准的问题,采用了一种新型无传感器控制技术即高频信号注入法,来检测转子速度和位置信息.基于高频信号注入法在永磁同步电机无传感器控制理论上做了详细的论述,设计了滤波环节和外差环节,并构建转子观测器以获取转子速度和位置信息.重点对低速情况进行了仿真实验.仿真所得结果表明,高频注入法于低速状态时能够适用,并且可以准确检测出转子速度和位置信息.
Abstract:
In view of to the conventional problem that when motor is running at low speed rotor position detec-tion is inaccurate,the method of high frequency signal injection was studied to deal with a new sensorless con-trol technology to detect the rotor speed and position information. High frequency signal injection method inpermanent magnet synchronous motor sensorless control theory was discussed in detail，the filter and hetero-dyne link were designed , and the rotor observer was built to acquire the information of rotor speed and posi-tion ， a simulation of low speed was focused on. The simulation results show that sensorless control technologybased on high frequency signal method is applicable to low speed,and accurately detect the rotor speed andposition information.
