Title:
MULTI-MOTOR CONTROL MODULE AND MOTOR DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/027557
Kind Code:
A1
Abstract:
The present invention provides a multi-motor control module and a motor driving system. The multi-motor control module comprises: at least two motor engine control units used for providing control signals for respective corresponding motors; a sampling unit used for sampling a phase current of each motor; a processor used for sequentially reading sampled data; a first coordinate transformation unit used for sequentially transforming a three-phase current sampling signal of each motor from a three-phase stationary coordinate system to a two-phase stationary coordinate system and a two-phase rotating coordinate system; a motor angle estimation unit used for estimating angles of the motors; a second coordinate transformation unit used for transforming, on the basis of the motor angles of the current motors, an output signal of the first coordinate transformation unit from the two-phase rotating coordinate system to the two-phase stationary coordinate system; and a motor control signal generation unit used for generating space vector pulse width modulation signals corresponding to the motors. The present invention reduces the cost of chip design, development and manufacturing, reduces the difficulty of solution development, shortens the development period, and implements the control algorithm in hardware, thereby improving the operating rate, and optimizing system control.
