| Abstract: | This paper introduces the current status of research and application on sensor data validation techniques in gas turbine engine ground test. It also details the implicit physics-based analytical redundancy for the correlation of multiple related data channels, as well as the statistic-based algorithms and signal time-frequency characterization algorithms to analyze individual data channel. A framework of methodology development for sensor data validation is proposed. |
