摘　　要：本文主要介绍了卡尔曼滤波算法在试车台数据采集系统的应用。重点阐述了卡尔曼滤波原理、试车台数据采集原理、其他数字滤波器在采集系统中的应用。文中以一阶卡尔曼滤波为例结合现场实际数据采集系统对比传统巴特沃斯滤波器,充分对比后,验证了卡尔曼滤波算法相比传统滤波器对于滤除PLC数据采集系统中随机干扰的优越性。This paper mainly introduces the application of Kalman filter algorithm in test bench data acquisition system, and focuses on the principle of Kalman filter, the principle of data acquisition of test bench, and the application of other digital filters in the acquisition system. In this paper, the first-order Kalman filter is used as an example to compare the traditional Butterworth filter with the actual data acquisition system in the field. After sufficient comparison, the superiority of Kalman filter algorithm compared with traditional filters for filtering out random interference in PLC data acquisition systems is verified.
