5285010600       OCT-00-25-0300-31-0-2-0-0-11-0000-0000-2為了建立液壓伺服系統(tǒng)故障模型,需要辨識液壓系統(tǒng)的結(jié)構(gòu)參數(shù),以流量、

壓力為觀測變量,以流量-壓力系數(shù)/Ce、流量增益系數(shù)iCq、液壓油特性為自

變量,建立3元線性回歸模型,分別辨識在加速、減速、恒速工況下的結(jié)構(gòu)參數(shù)。

液壓實(shí)驗(yàn)設(shè)備結(jié)構(gòu)如圖4-4所示。

根據(jù)式(4-15),模型Z將通過參數(shù)0反映故障形式與故障程度。如圖4-3所

示。首先,獲取不同工況下的觀測參數(shù);然后,將觀測參數(shù)代入模型Z;zui后以

0為回歸系數(shù),進(jìn)行線性回歸,辨識故障參數(shù)(9。
