Construction of Permanent Magnet Synchronous Motor Variable-Parameter Model

摘要：

　　Permanent magnet synchronous motor output characteristics can be expressed with its voltage equation,torque equation and motion equation.Parameters including inductance,resistance,flux linkage,damping coefficient and moment of inertia is regarded as constant in traditional motor models.However,the presence of magnetic saturation,cross-coupling and harmonics make the parameters variables.This paper analyzes causes and effects of the phenomena.Based on the constant parameter model of permanent magnet synchronous motor,the paper presents functions of flux linkages on d-axis current,q-axis current and rotor position angle.Building a motor model with the functions,permanent magnet synchronous motor variable-parameter model is constructed.
