| 摘 要： | 针对液压电机故障信号的特性,介绍了Kalman滤波及其递推算法在信号处理上的应用给出了时间序列自回归(AR)模型建立信号状态方程和观测方程的方法,并在这两个方程的基础上结合Kalman递推算法对信号进行滤波.通过有效的仿真和实际验证表明:利用Levinson-Durbin算法获得AR系数建立信号模型,再通过Kalman递推能够有效的达到滤波的效果.

| Abstract: | According to the characteristic of hydraumatic motor signal,the principle and recursion algorithm of Kalman filter are introduced and the methods of establishing state and measurement equation based on time series auto recursive model are given out.A way of signal filtering is poroposed according Kalman recursion algorithm and the equations.After system simulation and practical certification,the result shows its affectivity to remove noise from vibration signal by creating the model using AR coefficient com... |
