摘　　要：针对连续回转电液伺服马达系统中存在着某些参数的不确定性及外部干扰,在建立系统数学模型的基础上,研究能够克服对象不确定性和外部干扰的QFT鲁棒控制方法,设计了QFT控制器,通过定量反馈的控制方法提高系统的整体性能.与复合PID控制器进行了比较,理论和仿真结果均证明了所设计控制器的有效性.Aimed at the parameter uncertainties and external interference in continuous rotary electro-hydraulic servo motor system, a QFT robust control method, which can overcome the uncertainties and external interference, is presented based on the building of a mathematical model of the system, and a QFT controller is designed. The quantitative feedback control method is employed to improve the overall performance of the system. The results of theoretical analysis and simulation research prove that the designed controller is effective in comparison with PID compound controller.
