与伺服阀、比例阀相比,高速开关电磁阀价格低廉、抗污染力强,但控制精度较差。本文结合一个实际系统,对近年来通过改进高速开关阀PWM控制技术以提高系统控制精度的方法作一简单介绍。
Compared with the servo valve, proportional valve, high-speed switching solenoid valve inexpensive, strong anti-pollution, but the control accuracy is poor. In this paper, a practical system, in recent years by improving the high-speed switching PWM control technology to improve the system control accuracy of a brief introduction.
