Initial Rotor Position Estimation for Automotive Dual Three-phase Motors Using Voltage Injection in Harmonic Plane
摘要
Abstract
Initial rotor position estimation(IRPE)is crucial for the sensorless control startup and high-performance operation of automotive dual three-phase permanent magnet synchronous motors(DTP-PMSM).Based on the established mathematical model of pulse voltage injection and the salient polarity of leakage inductance in the harmonic subspace,an IRPE method based on voltage pulse sequence injection in the harmonic subspace was proposed.Pulse sequences were injected into the harmonic subspace to suppress torque disturbance,and an overdetermined fitting algorithm was adopted to extract rotor position information from the current response.Bench test results verified the effectiveness of the proposed method.The high-precision initial rotor position identification was achieved and the torque disturbance was significantly reduced,thus resolving the inherent dilemma of traditional methods that fail to balance the estimation accuracy of initial rotor position and low noise and vibration performance.关键词
