摘　　要：基于参数递推辨识与信号滤波同时并行处理 ,建立通用板形检测信号除噪方法 ,编制RPEM -KF自适应滤波算法程序。仿真结果表明该法除噪效果明显 ,滤波前后信号的标准差比值 Ve/Vn =4 63 % ,最大误差比值Me/Mn =4 13 %。Based on parallel implement of parameter recursive recognition and signals filtering, a general method is established to remove the harmful noise from the flatness detection signals, and a RPEM KF adaptive filtering program is developed The simulation result shows that the noise can be effectively removed by using this method, the ratio of standard errors of pre and post filtering signals V e/ V n=4 63% and the ratio of maximum errors M e/ M n=4 13% It is applicable in real time controlling
