说明：  基于 Proteus 的等离子切割机控制系统的仿真设计 本文介绍了 Proteus 软件的特点和功能以及基于 Proteus 进行单片机系统开发的过程。在 Proteus 环境下结合Keil C 对空气等离子切割机的控制系统进行了调试仿真，仿真证明，该系统可 以完成空气等离子切割机的整体控制功能。在 Proteus 环境下完成单片机系统的硬件设计和软件 调试，可以降低设计成本，缩短开发周期，提高效率。
(Design and simulation of digital control system of air plasma cutting machine based on Proteus Introduced the characteristic and function of Proteus software, as well as the process of the development of MCU system based on Proteus. Control system of air plasma cutting machine was debugged and simulated under Proteus and Kiel C, The simulation had proven that this system can able to complete the air plasma cutter s all control function, and therefore design and simulation of control system of digital power supply of air plasma cutting machine used Proteus can reduce development cost, short the development cycle and raise the efficiency.)
