摘　　要：实现了基于PID算法的电液比例阀控制系统,系统可以有效解决传统比例阀技术的问题,其控制功能强大、维护成本低、系统控制精度高且结构相对比较简单。在系统电路设计中,以单片机控制系统、数字PID算法和PWM技术为研究对象,设计了系统电路和功率放大电路,并编写了系统控制程序。This paper studies the PID algorithm based on electro-hydraulic proportional valve control system, it is a kind of software instead of part of the complex hardware control system, this system can effectively solve the traditional proportional valve technical problems, and its strong control function, low maintenance cost, the control system has high control precision and system structure is relatively simple. In the circuit design of the system, the single chip microcomputer control system, the digital PID algorithm and PWM （pulse width modulation） technology as the research object, designs the system circuit and the power amplification circuit, and writes the system control program.
