摘要: PID控制是反馈控制系统中最常用的控制方法。在托卡马克装置中,等离子体的行为是很难精确预测和控制的。托卡马克等离子体控制系统中包括了对不同控制对象的PID控制。基于数字滤波技术设计的低通滤波PID算法,通过滤掉误差信号中的噪音信号从而提高了算法的控制效果。该算法在等离子体控制系统中得到了很好的应用。

Abstract: PID control is the disciplinarian frequently used in feed-back control system. In Tokamak device, the behavior of plasma is difficult to analyze and control. The plasma control system of Tokamak consists of PID control for different objects. The low pass filtering PID algorithm based on the digital filtering technology is designed. The algorithm enhances the control precision by filtering the noise intermingled in the error signal and is well used in the plasma control system.

Key words: plasma control system, low pass filtering, PID control algorithm
