Abstract

A brushless direct current motor control method based on RISC-V. An RISC-V core chip is connected to a motor controller of a brushless direct current motor, and the RISC-V core chip is in butt joint with a motor control system corresponding to the motor controller. The RISC-V core chip is used to acquire working data of the brushless direct current motor, and the working data is uploaded to different motor operation function programs; analyzing and processing the working data through a motor operation function program to obtain a corresponding motor working state analysis result; and finally, according to a motor working state analysis result, a corresponding control instruction is sent to the brushless direct current motor, and the working state of the brushless direct current motor is adjusted. According to the control method, the RISC-V core chip is connected into the motor controller of the brushless direct current motor, and the RISC-V core chip can be used for transplanting an operating system, so that different functional programs of the brushless direct current motor can be conveniently operated, and the compatibility of the brushless direct current motor to the different functional programs is improved.

Description

【Technical field】 [0001] The invention relates to the field of motor control and management, in particular to a RISC-V-based brushless DC motor control method. 【Background technique】 [0002] The brushless DC motors of the existing electric vehicles are all adjusted using a general embedded computing framework, and the embedded computing frameworks are integrated with a specific operating system to complete the control of the brushless DC motors. The above methods cannot perform universal control of the BLDC motor, reduce the compatibility of the BLDC motor with different operating systems, and cannot carry out effective post-maintenance and upgrade improvements to the BLDC motor, reducing the control stability of the BLDC motor. sturdiness and reliability. [Content of the invention] [0003] The purpose of the present invention is to provide a RISC-V-based brushless DC motor control method, which connects the RISC-V core chip into the motor controller of the brushless DC...
