Research And Design Of The Stepper Motor Engraving Control System Based On ARM And FPGA

Along with the growing demand of Engraving Control product, Engraving Control technology is developing very fast. Recently, the developments of electronic information and some other high-tech technologies provide a larger development space and a broader market for the products of engraving control. For domestic engraving control products, there still exists much larger upside potential on the speed, accuracy and cost-effective.In order to achieve the high-speed, high-precision engraving control systems. This paper study on the stepper motor engraving control system based on ARM and FPGA.In this paper, according to the engraving control system functional requirements and performance indicators, proposed a engraving control systems which ARM and FPGA as core processor, built the hardware platform with STM32series ARM chip STM32F103ZE and ALTERA Corporation Cyclone series FPGA chip EP1C3T144C8N as the core, and designed the hardware circuit for peripheral modules. Then, improved the traditional DDA(Digital Differential Analyzer) interpolation algorithm to enhance interpolation speed, modeled and simulated the S-shaped curve acceleration and deceleration control algorithm with Matlab software. Using the Verilog HDL hardware description language to achieve those two control algorithms on FPGA platform, thus completed the interpolation control functions. Programmed on ARM platforms to achieve the functions of G-code file Parsing and forward-looking, interpolation parameter passing and interactive, constructed the engraving control system with continuous processing function, and it can be run offline. Finally, tested various functions and technical parameters of this system, and the studio-line testing with other CNC equipment machine shows that the system is stable, convenient for users to control, it is a high cost-effective and full-featured engraving control system. This system eventually realized to be products.Research on the multi-microprocessor engraving control system shows that the main co-processor development mode shortens the development cycle, reduces costs, and improves the processing speed and accuracy of the system. In future, we can carry out research on Engraving Control Technology and Error Compensation Technology, which can further enhance speed and accuracy of the system.
