In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.

Combined the geological analysis with analogue modeling experiments,the evolution of the Yinggehai basin could be divided into four main stages:(1) Before 42Ma,controlled by the southeastward extension of the Beibu Gulf basin on the northern continental margin,the Yinggehai basin experienced dextral pull-apart.Bounded by NS-trending Yingxi fault,the transtensional areas mainly are the northwest part and along the eastern boundary of the basin.(2) From 42 to 21Ma,the development of the main rift body in Yinggehai basin was mainly controlled by the southward slip and clockwise rotation of the Indochina block along the Red River fault zone,and the sedimentation was strengthened due to the sinistral transtension.In the east,the subsidence is deepened due to the dextral transtension.(3) From 21 to 10.4Ma,the sinistral movement of the Indochina block slowed down to still.From 21 to 15.5Ma,the northwest part of the basin began to inverse locally because of post-rift thermal subsidence of the whole basin.(4) From 10.4Ma to present,the basin was affected by the dextral movement of the South China block along the Red River fault zone and thermal accident in a new phase at 5Ma.
