Abstract: In view of the many shortcomings of the existing voice coil motor galvanometer drive controller, a heterogeneous drive control based on Field Programmable Logic Gate Array (FPGA) and Advanced Reduced Instruction Set Machine (ARM) was proposed, and the peripheral drive circuit was designed according to engineering requirements. Functionswere divided according to the respective advantages of FPGA and ARM processors. ARM was mainly used for system initialization, signal sampling, analog signal output, position loop and current loop closed-loop control, etc. FPGA was mainly responsible for the processing of laser marking image point data sets, host computer communication function, data exchange with ARM, etc. The simulation experiment on the driving circuit shows that the circuit design is reasonable and can meet the requirements.

Key words: motor drive control, linear voice coil motor, field programmable gate array(FPGA), advanced RISC machine(ARM)
