摘要 针对动态扭矩传感器在数据采集过程中存在的脉冲干扰、高斯噪声干扰等引起的误差问题,提出采用滑动平均滤波与卡尔曼滤波算法相结合方式对卡尔曼滤波算法进行改进。既提高了动态扭矩传感器的测量精度,又保证了数据采集系统的频率特性。 Aiming at the error problem caused by pulse interference and Gaussian noise interference in the process of data acquisition of dynamic torque sensor,a combination of moving average filter and Kalman filter algorithm is proposed to improve the Kalman filter algorithm.It not only improves the measurement accuracy of dynamic torque sensor,but also ensures the frequency characteristics of data acquisition system.
