Continuous globally exponential rigid-body angular velocity estimation from attitude measurements
Ioannis Sarras
A continuous solution is proposed to the problem of uniform global exponential estimation of the angular velocity for rigid bodies by means of direct attitude measurements. The pro…
A global exponential observer for velocity-aided attitude estimation
Philippe Martin, Ioannis Sarras, Minh-Duc Hua +1
We propose a simple nonlinear observer for estimating the attitude and velocity of a rigid body from the measurements of specific acceleration, angular velocity, magnetic field (in…
A global observer for attitude and gyro biases from vector measurements
Philippe Martin, Ioannis Sarras
We consider the classical problem of estimating the attitude and gyro biases of a rigid body from vector measurements and a triaxial rate gyro. We propose a simple "geometry-free"…
A semi-global model-based state estimator for the quadrotor using only inertial measurements
Philippe Martin, Ioannis Sarras
We propose a nonlinear observer to estimate the state (orientation and in-plane velocity vector) of the quadrotor, based on a drag-force-enhanced model. It is an alternative to rec…
