摘要
从实际应用的角度出发,提出利用跟踪微分滤波器抑制机翼挠曲变形产生的影响,通过杆臂效应补偿消除干扰加速度,用延时补偿算法减少由数据传输延迟造成的量测信息误差。在此基础之上,采用"速度+姿态"匹配方案,研究了基于H_∞滤波估计的快速传递对准方法。大量数值仿真、静态试验、动态跑车试验表明,这些方法有收敛速度较快、精度较高的特点,并具有较强的抗干扰能力。试验也验证了传递对准方法的有效、可行,能满足控制系统对导航信息的精度要求。
The paper is concerned with the transfer alignment technique in air-to-ground weapons. Three compensation methods was proposed： （1） Using Tracking Differentiator（TD） filter to compensate the error caused by wing deformation; （2） using accelerate compensation to eliminate the error caused by arm level effects; （3） Compensate the filter measurement errors caused by the delay of data transfer. A rapid transfer alignment method based on H~ filter＇s estimation was studied using ＂velocity ＋ attitude＂ matching scheme. Large amount of simulations, static and dynamic tests show that the method could estimate the misalignment rapidly with high precision and anti-jamming capability. They also prove that the method is effective and feasible, and can satisfy the requirements for the navigation information precision.
