Abstract

The invention discloses a high-stability control method for motor torque. The method comprises the following steps of collecting motor torque information through a data collector, building a data model, and setting a quadratic quantitative longitudinal tracking performance sub-target, judging whether the distance between the collected motor torque information and the cloud server exceeds the expectation or not, recording the minimum braking distance of different motor rotation conditions, estimating a torque information coefficient in real time when the motor rotates, and looking up a table according to an estimation result to obtain the motor torque information in a minimum safety range. According to the high-stability control method for the motor torque, high-stability control over the torque of the motor can be accurately and rapidly achieved, and when the torque deviates from the set value, the torque of the motor can be rapidly adjusted through the control method, so that the motor operates stably, the heat removal capacity is enhanced, and the rotating quality of the motor is improved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a high-stability control method for motor torque. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation torque. Motors are divided into DC motors and AC motors according to the power used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). The working pri...
