摘　　要：为减少数控机床在加工中的定位误差,依照误差补偿法,文中提出了基于DSP和FPGA的误差补偿系统,并对其硬件模块进行了设计与实现。通过芯片特点分析,该系统硬件构架选择采用浮点型DSP和FPGA,以满足数控系统的实时性和高精度控制要求。研究中主要利用C和Verilog HDL语言;各模块采用纯硬件模块实现,介绍了主要模块的设计过程,并经过仿真验证了设计的正确性。该补偿系统通用性高、适用面广、结构简单。In pursuit of improving the positioning accuracy during CNC machining,according to the principle of error compensation,a new error-compensating system based on DSP and FPGA is proposed in this paper,while designing and realizing the modules for the system. After the chip analysis,the method of using DSP and FPGA to design the hardware structure is decided with th aim of real-time performance and high precision for the control. The whole process of design is simply coding with C language and Verilog HDL to realize the hard modules. For the major function modules,this paper introduces the details and makes simulations,proving the correctness of the design. And the new system is characteristic of distinctive universality,wide applicability and simple structure.
