摘　　要：针对专用车发动机和底盘取力装置转速控制问题,提出了基于闭环反馈式自动控制方式的解决办法,该系统依据工作机转速信号与标准信号的比拟,在控制集成块中测算处理数字信号差,利用可编程控制器对步进电机的转速进行实时调整,从而驱动发动机转速控制系统实现二次调速功能。随着产品的进一步完善,可大大提高车载取力工作机的工作效率和工作质量,具有很高的实用价值。The autocontrol mode basing on closed loop feedback solves the rotate speed control of engine and PTO device for the special purpose vehicle. This system can adjust the rev of stepelectromotor by the programming controller which can receive the calculated digital signals from the controlling integration block after comparing the signal from PTO device with the standard signal. The efficiency and work quality of PTO device will be enhanced along with more perfecting on production and the system will have more practicality
