在近代控制中,需要对某一特定的运动目标进行跟踪监测,并需要对其下一时间的运动位置、运动方向、速度等信息进行预先估算,才能达到对目标的即时控制。本文简要讨论了用卡尔曼滤波算法对单个目标航迹进行预测,并借助于Matlab仿真工具,对实验的效果进行评估。 In modern control, we need to track and monitor a specific moving target, and we need to estimate the movement position, movement direction, speed and other information of the next time in advance, so as to achieve the immediate control of the target. This article briefly discusses the use of Kalman filter algorithm to predict a single target track, and with the help of Matlab simulation tool to evaluate the effect of the experiment.
