The classic approaches for fundamental frequencies smoothing , such as linear smoothing , median smoothing and linear interpolation , can not work well in the case of that fundamental frequency is not detected correctly and several continulus frames 傳統(tǒng)基音的平滑方法:線性平滑、中值平滑和一般的線性插值方法都不能很好地處理連續(xù)的基音頻率有隨機(jī)錯(cuò)誤點(diǎn)的情況。
Based on the analysis of autonomous underwater vehicle ( auv ) sensor failure , diagnosis methods corresponding to three kinds of sensor failure are presented , that is , through that no sensor output for a long time to diagnose the fault of sensor signal gathered keeping unchanged , linear smoothing to solve the vibration of sensor signal , wavelet transform to inspect the broken sensor signal 摘要在分析水下機(jī)器人傳感器故障形式的基礎(chǔ)上,對(duì)傳感器可能出現(xiàn)的三種故障形式分別給出了相應(yīng)的診斷方法,即通過傳感器長時(shí)間采集不到數(shù)據(jù)來診斷傳感器信息保持不變的故障,線性平滑濾波解決傳感器輸出振蕩,小波變換檢測傳感器信息的突變。
