Design of Broadband Automatic Level Control System Based on PID

针对宽带微波信号发生器中的自动电平控制系统,本文提出了一种基于PID的自动电平控制方案,实现微波信号发生器输出射频信号功率对给定值的自动跟踪,在宽频带范围内达到较高的功率准确度和分辨率。通过实验对设计的控制系统进行验证,实际使用结果证实了本文方法的有效性。

In this paper a control method for ALC system in a microwave signal generator based on PID is proposed. The power of radio frequency signal from the microwave signal generator has achieved auto tracking of a set value which has relative high power accuracy and resolution within a wide frequency band range. The ALC system has also been proved stable and high performance by experiment.
