摘　　要：提出了一种新的激光切割机的电源控制系统设计方案,该方案融入了FPGA技术,采用意法半导体公司的ARM为控制核心,优化了电路设计,增强系统整体的可靠性,从而实现了高稳定度的激光切割机电源驱动控制。采用MATLAB对参数限制条件进行拟合,简化了ARM程序。通过巴特沃斯型低通滤器对ARM输出的电压进行滤波,更好地抑制高频信号干扰,提高系统的精度。利用旋转编码器实现对参数的输入、液晶屏的显示以及整机的控制,操作简便。实际应用表明,电源控制系统具有智能化程度高、抗干扰能力强、精度高、运行稳定、操作方便、人机界面友好等优点。A new power supply control system for Laser Cutting Machine that combines FPGA technolo- gy with high-performance single-chip microcomputer （STMicroelectronics） ARM as controlling center is presented. It also optimizes the circuit design and increases the reliability of all system. The application of MATLAB to fit the constraint conditions of parameters simplifies the designed programs in the ARM. The output voltage signal of the ARM is filtered by a low-pass Butterworth filter, which restrains the high frequency interference and improves the system precision. The system is featured with a simple rotary encoders for parameters input and the display of the LCD. The practical applications show that the power supply control system is more intelligent, capable of anti-interference, precise, stable, friendly and convenient to control.
