数字电位器在风速控制系统中的应用

Application of Digital Potentiometer in Wind Speed Control System

通过对数字电位器的结构及性能分析,发现它能够实现风速控制系统中电流环功能。由于数字电位器具有普通电位器所没有的数字化调解以及很高的抗干扰能力,把它用于风速控制系统,不但更容易与主程序接口,便于程序自动控制,而且大大增强风速控制系统的抗干扰能力。

This article analyzed digital potentiometer structure and its performance and found it could be used to form the current loop in the wind speed control system. Because the digital potentiometer has characteristics such as accurate adjustment and stability , the arm position data could be long - term preserved and renovated, and it is vibration-proof, pollution-proof, be connected with the computer easily. Besides it has Stable performance, long life time, so it has better antijamming ability than ordinary potentiometer. Thus it is very suitable to implement it in the wind speed control system. The application of digital potentiometer is convenient not only to interface with main program, but also autocontrolled by program. Further more it improves antijamming ability greatly in the wind speed control system.
