Homogeneous Approximation, Recursive Observer Design, and Output Feedback
We introduce two new tools that can be useful in nonlinear observer and output feedback design. The first one is a simple extension of the notion of homogeneous approximation to ma...

Friction observer and compensation for control of robots with joint torque measurement
— In this paper we introduce a friction observer for robots with joint torque sensing (in particular for the DLR medical robot) in order to increase the positioning accuracy and ...

A control theory approach to the analysis and synthesis of the experimentally observed motion primitives
Recent experiments on frogs and rats, have led to the hypothesis that sensory-motor systems are organized into a finite number of linearly combinable modules; each module generates...

Extending noninterference properties to the timed world
Most previous work on information flow in process algebras has been based on untimed models of concurrency. It is obvious, however, that an observer might well use time to gain i...
