A nonlinear disturbance observer for robotic manipulators [PDF]

open access: yes, 2000
A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...

Develop a robust nonlinear controller for large aircraft by applying NDI, SMC and adaptive control [PDF]

open access: yes, 2012
A nonlinear dynamic inversion (NDI) controller and a sliding mode controller are developed for large civil transport Boeing 747 in this thesis. Furthermore adaptive control theory is applied on both NDI controller and SMC controller to improve the ...

Sedimentary processes in the Thau Lagoon (France): From seasonal to century time scales [PDF]

open access: yes, 2007
As a part of the MICROBENT programme, an investigation of the sedimentation framework was carried out at the water-sediment interface in the Thau Lagoon (French Mediterranean coast). Two main sites, C4 in the middle of the lagoon and C5 near oyster farms,

Influence of shellfish farming activities on nitrification, nitrate reduction to ammonium and denitrification at the water-sediment interface of the Thau lagoon, France [PDF]

open access: yes, 1997
The seasonal patterns of nitrification, denitrification and dissimilatory ammonium production (DAP) rates were studied in the sediment of 2 stations in the Thau lagoon (south of France).

Experimental External Force Estimation Using a Non-Linear Observer for 6 axes Flexible-Joint Industrial Manipulators [PDF]

open access: yes, 2013
This paper proposes a non-linear observer to estimate not only the state (position and velocity) of links but also the external forces exerted by the robot during Friction Stir Welding (FSW) processes.
