摘要
针对无人机速度信号估计存在噪声等问题,研究一种基于强跟踪滤波与卡尔曼滤波对未知信号进行估计的滤波算法。在预测先验误差协方差时引入渐消因子,减弱过去数据对滤波效果的影响,从而提升滤波器的响应速度与精度。对无人机自驾仪估计的速度信号进行滤波处理。结果表明,强跟踪卡尔曼滤波器信号响应更快,超调更小,精度更高。
Aiming at the problem of noise in UAV speed signal estimation,a filter algorithm based on strong tracking filter and Kalman filter was proposed to estimate unknown signal.When predicting the prior error covariance,the fading factor was introduced to reduce the influence of the past data on the filtering effect,and thus improved the response speed and accuracy of the filter.The speed signal estimated by the UAV autopilot was filtered.The results showed that the signal response of strong tracking Kalman filter was faster,the overshoot was smaller and the precision was higher.
