Abstract

The invention discloses a motor control fault tolerance processing method and an apparatus thereof, a motor and an electric vehicle. The apparatus comprises a motor position sensor, a decoding circuit, a current sensor, a motor rotating speed sensor, a calculating circuit and a processing circuit. Whether a current position theta n of a motor rotor is in a set position scope determined according to a previous position theta n-1 of the motor rotor, a current load of the motor and a current rotating speed of the motor is determined. If the current position theta n of the motor rotor in a set sampling period does not belong to the set position scope, according to the previous position theta n-1 of the motor rotor, the current load of the motor and the current rotating speed of the motor, a correction position theta n' of the motor rotor is determined. By using the method, the apparatus, the motor and the electric vehicle of the invention, a condition that the motor is out of control can be effectively prevented; a fault tolerance capability is possessed; control continuity and stability are maintained; and a condition that a vehicle is out of control is prevented.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor control fault-tolerant processing method and device, a motor and an electric vehicle. Background technique [0002] Traditional motor control is conventional closed-loop control, and external interference and vibration will affect the operation of the motor. The running state of the motor changes with the signal of the motor position sensor. When the signal of the motor position sensor is disturbed, the running state of the motor will also be disturbed. It will cause damage, and it will also damage the motor body. [0003] Therefore, it is necessary to provide a motor control fault-tolerant processing device to solve the above-mentioned technical problems existing in the prior art. Contents of the invention [0004] A technical problem to be solved by the present invention is how to provide a motor control fault-tolerant processing device or method that can effectively prevent m...
