Abstract

The invention provides a permanent magnet synchronous motor control method and device, a motor controller and an intelligent automobile, and the method can carry out the harmonic current detection of a first excitation current and a first torque current, outputs a harmonic excitation current and a harmonic torque current after the detection, processes the harmonic excitation current and the harmonic torque current and thenoutputs harmonic excitation voltage and harmonic torque voltage ; and the first excitation current and the first torque current are used as input parameters of PI adjustment, and the second excitation current and the second torque current are used as output parameters of PI adjustment to carry out PI adjustment so as to form an adjusted excitation voltage and an adjusted torque voltage, so that a motor control algorithm is optimized, the motor torque fluctuation is effectively reduced, the torsional vibration of a driving system is reduced, and the purposes of reducing motor torque fluctuation, improving the smoothness of a motor system and improving the comfort and drivability of the whole vehicle are achieved.

Description

technical field [0001] This application relates to the technical field of electric vehicles, specifically a permanent magnet synchronous motor control method and device, a motor controller and a smart car. Background technique [0002] Permanent-magnet synchronous motor (Permanent-Magnet Synchronous Motor; PMSM) not only has a series of advantages such as simple structure, reliable operation, convenient maintenance, etc., but also has many characteristics such as high operating efficiency, good speed regulation performance and no excitation loss, so it is widely used in today's national Applications in various fields of the economy, such as medical equipment, instruments, aerospace, electric vehicles and household appliances, are becoming more and more popular. [0003] The torque of the motor is the strength of the motor's rotation. Torque fluctuations not only cause the vibration of the motor itself, but also the parts that are in direct or indirect contact with the motor ...
