Description

technical field [0001] The invention belongs to the field of motor control, and in particular relates to a SoC-FPGA-based single-chip motor control device and a control method thereof, which are mainly used to realize single-chip control of motors. Background technique [0002] In the field of motor control, TI's 2000 series DSP can be said to have occupied a large market for a long time, but with the continuous improvement of control requirements, such as faster computing speed, more peripherals, and more diverse communication interfaces etc., all make existing motor control chips have great limitations. [0003] For example, in the current control structure, FPGA is generally used for interface and peripheral expansion, while some commonly used communication interfaces such as Ethernet, USB and other interfaces need to be expanded with ARM chips. Motor control chips, etc. Although these methods can solve the problem to a certain extent, they not only increase the complexi...

Problems solved by technology

[0003] For example, in the current control structure, FPGA is generally used for interface and peripheral expansion, while some commonly used communication interfaces such as Ethernet, USB and other interfaces need to be expanded with ARM chips. Motor control chips, etc. Although these methods can solve the problem to a certain extent, they not only increase the complexity of the system, reduce the reliability, but also increase the cost of hardware and development and maintenance a lot

[0004] At present, although there are FPGA-based motor control algorithms proposed, they are only limited to the algorithm level, and there is no solution for the entire control system.

[0005] In terms of SoC-FPGA, although there are literatures describing its application in motor control, there is no feasible application plan for how to realize SoC-FPGA-based single-chip control.
