专利汇可以提供Abnormality diagnosing method of sensor group专利检索,专利查询,专利分析的服务。并且PURPOSE:To identify easily whether an abnormal sensor is present or not and the abnormal sensor itself by calculating an error vector from the relational equation between an actual sensor output and a normal sensor time-series output. CONSTITUTION:A diagnosing device 1 reads the control input value U(k) and state observed value Y(k) of a plant 2 specific sampling time and uses them to diagnose the abnormality of a sensor group. In this case, (k) is the number of steps and X(k) is the quantity of state in the plant. The relation among sensor time-series outputs when sensors are in normal operation is found by an equation 1 from the dynamic model of the plant. In the equation, A(k-j) and B(k-j) are matrixes of (q) rows by (q) columns and (q) rows and (r) columns. Further, the sensor error vector DELTAE showing a specific kind of variation of sensors is calculated from the actual sensor output and the equality 1 and whether an abnormal sensor is present or not and the abnormal sensor itself are identified from mutual positiosn in vector space.,下面是Abnormality diagnosing method of sensor group专利的具体信息内容。
