对于试验过程中出现的以下问题，油门杆高速运动中输入轴力矩控制的响应速度较慢，输入轴力矩控制对油门杆位置控制的扰动，以及输入轴力矩脉动现象，提出了解决方法，并且从理论上加以验证。 - First in this paper , the control methods of electric actuators was studied and analyzed . the retangcle - wave permanent magnet brush - less motor is used for servo - motor , the reason of its torque ripple and the way to eliminating or suppession is analyzed and elaborated . in order to achieved wide - speed range , the method of variable structure control ( vss ) was used . ,
论文分析了飞机电力作动系统的基本要求，选用方波直流无刷电机作为执行电机，采用重叠换向法、变结构控制策略和转速、电流双闭环pid控制方案，很好地解决了其固有的低速转矩脉动现象，达到调速范围宽、转矩脉动小的设计要求。 - A maximum reflecting of 53 . 8 % was obtained . furthermore we advanced , for the first time to our knowledge , which the self - pulsation of phase conjugation wave was related to the incident power intensity . through calculation we concluded that the phase conjugation was instable when the incident power density ranged in 700 - 1240mw / cm2
实验中特别着重分析了位相共轭光不稳定，即自脉动现象，首次得出位相共轭光自脉动与入射在晶体上功率密度有关的结论，即在700 1240mw cm ’的入射功率密度下，有位相共轭光不稳定，即自脉动现象产生。
