摘要:
为了解决新型无位置传感器永磁同步电机的起动问题,提出了一种在电机静止状态下检测转子位置的新方法。该方法在算法上改进了传统的旋转高频电压注入法,使得可以更为快速、准确的检测出转子初始d轴位置。并且针对传统旋转高频电压注入法无法检测出转子永磁体极性问题,在d-q旋转坐标系下,通过分析永磁同步电机d轴磁链和定子电流之间的关系,利用d轴电流的泰勒级数展开,提出了根据定子铁芯非线性磁化特性获得判别N/S极极性信息的新方案,并建立了系统仿真模型。仿真结果验证了这种方法的有效性和可行性。此方法同样适用于永磁同步电机在中、低速时的转子位置检测。
Abstract:
A new approach to estimate the initial rotor position when permanent magnet synchronous motor (PMSM)is standstill is proposed. The approach proposed to improve the conventional rotating high frequency voltage signal injection method in the arithmetic. The position of d-axis can be faster and more accuratly calculated than the traditional method. In order to resolve the problem in detecting the polarity of the rotor magnet of the traditional method,a new scheme was also presented. Based on the non-linear mag...
