Velocity Estimation via Thau Observer for a PMSM in Chaotic Regime and its Physical Validation
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2012Abstract In this paper, we design a Thau observer for the permanent-magnet synchronous motor (PMSM) model, which estimates the angular velocity from the measurement of currents. We apply some Bounds obtained from the localization of compact invariant sets of the system describing dynamics of a PMSM.

Benthic macrofauna and sediment reworking quantification in contrasted environments in the Thau Lagoon [PDF]
Estuarine, Coastal and Shelf Science, 2007 As part of the Microbent-PNEC Program: ‘‘Biogeochemical processes at the wateresediment interface in eutrophicated environment’’, the aim of this work was to specifically investigate and quantify the relationships between macrobenthos and sediment ...

In this paper, we propose a Fault Tolerant Control (FTC) strategy for a reconfigurable quadrotor with foldable arms, to deal with a total loss of one of its rotors. The proposed strategy allows adapting the configuration of the quadrotor when one of its rotors is lost.

Thau-Luenberger observers for TS fuzzy systems
Ninth IEEE International Conference on Fuzzy Systems. FUZZ- IEEE 2000 (Cat. No.00CH37063), 2002Deals with local fuzzy Thau-Luenberger observers for nonlinear plants. A nonlinear plant is approximated by a Takagi-Sugeno (TS) fuzzy multiple model with affine subsystems for which local linear fuzzy observers are constructed. Analysis of stability conditions for the complete observer is made and a design procedure based on linear matrix inequalities

An Adaptive Thau Observer for estimating the time-varying LOE fault of quadrotor actuators
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013Fault Estimation (FE), as the central part of an Active Fault Tolerant Control System (AFTCS), detects and estimates the magnitude of a fault when a fault/failure occurs. Especially for a quadrotor UAV (Unmanned Aerial Vehicle) system, it is necessary and helpful to estimate fault severity when its actuator has a partial loss of effectiveness (LOE) and

Robust Fault Estimation on a real quadrotor UAV using optimized Adaptive Thau Observer
2013 International Conference on Unmanned Aircraft Systems (ICUAS), 2013As a result of modeling uncertainties, data decade unbalanceand noise, Fault Estimation (FE) for real quadrotor is rough with low accuracy when model observer based FE scheme-Adaptive Thau Observer(ATO) is applied. Based on these issues, this paper proposes a comprehensive optimization approach on FE accuracy for quadrotor using ATO.
