State and multiplicative sensor fault estimation for nonlinear systems [PDF]
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013 This paper addresses the state and sensor fault estimation for nonlinear systems represented by Takagi-Sugeno (T-S) models. The considered faults are time-varying and with multiplicative effect on the sensor output signals. The proposed estimation procedure is based firstly on the sector nonlinearity approach using the convex polytopic transformation ...

IMU Sensor Fault Diagnosis and Estimation for Quadrotor UAVs
IFAC-PapersOnLine, 2015 Abstract This paper presents a fault detection, isolation and estimation scheme for sensor bias fault in inertial measurement units (IMUs) of quadrotor unmanned air vehicles (UAVs). By using estimated roll and pitch angles obtained using a sliding-mode observer method, a diagnostic algorithm is developed for detecting, isolating and estimating sensor
