摘要
针对运载火箭自适应增广控制(AAC)方法输出抖动问题提出一种改进AAC控制方法,该方法在AAC基础上增加弹性辨识算法来辨识系统弹性振动频率,通过设计陷波滤波器来抑制系统弹性振动,从而消除自适应增益输出抖动问题。仿真结果表明,该方法继承AAC抗干扰能力强的优点,避开AAC输出抖动的缺点,有效提高了系统鲁棒性。
An improved AAC control method is proposed for the output jitter of the AAC method of the launch vehicle.An elastic recognition algorithm is added to the AAC for identifying the elastic vibration frequency,and the system’s elastic vibration is suppressed by designing the notch filter which solves adaptive gain jitter problem.The simulation results show that this method has the strong anti-jamming ability,avoids the disadvantages of output jitter and improves system robustness effectively.
