QFT控制在连续回转马达位置伺服系统中的应用

Application of QFT Controller in Continuous Rotary Motor Position Servo

连续回转马达位置伺服系统中存在着参数不确定性及外部干扰,QFT是一种频域设计方法,能有效克服马达系统的不确定性并抑制摩擦转矩干扰。文章分别设计了QFT控制器和PID控制器,并进行仿真对比分析,理论和仿真结果均证明了所设计QFT控制器的有效性。

In continuous rotary electro-hydraulic servo motor system,the uncertainty of parameters and external friction disturbance should be considered.The QFT controller,based on frequency,can overcome the uncertainty and external interferences effectively.QFT controller and PID controller are designed in this paper,and the effect of each controller is compared through simulition.The theory and the result of simulation both prove the effectiveness of the designed QFT controller.
