This technical note considers a solution to an output regulation problem for control systems on the special Euclidean group $SE(n)$. The proposed solution consists of a convergent observer together with a certainty equivalence implementation of an almost globally stable state feedback law. The design of the observer and the state feedback are carried out independently. We show that all closed loop...
The state consensus problem among groups of linear parameter-varying (LPV) systems is addressed. The systems are assumed to have an identical LPV structure. We consider both homogeneous groups, where the time-varying parameters are identical, and heterogeneous groups, where the parameters can be different for all agents. Motivated by relative sensing we assume static, possibly parameter-varying, diffusive...
Automatic tools for the propagation of contours and surfaces in time series of CT images (4DCT) are necessary e.g. for dose calculation in radio-therapy-planning. The state of the art method is the registration of 3-D frames of the sequence on a static reference volume or the registration of consecutive volume pairs. Based on the computed vector fields, the contours and surfaces are then propagated...
