摘　　要：针对EAST(Experiment Advanced Superconductive Tokomak)托卡马克装置中多个子系统采用PID控制,本文介绍一种以根轨迹法为理论基础,利用MATLAB控制系统工具箱中的GUI工具SISOTOOL调整根轨迹的形状,同时通过实时观察典型输入响应的波形得到符合要求的控制参数。该方法直观,适用于线性、非线性系统,可根据不同的系统指标整定出不同的PID参数。As for PID control is used in some sub-system in EAST Tokomak equipment,we introduce a method which is base on root locus and sisotool in MATLAB o We adjust the form of root locus by sisotool,and we observe the input response wave which is changed with root locus real time while tuning the control parameter until the form of root locus is in our mind. This method is easy, and is appropriated for both linear and nonlinear system,and we can adjust different PID parameter via different system performance index .
