What has Instrumental Variable method to offer for system identification?

This paper gathers several experiences of using instrumental variable method in different contexts: closed-loop system identification, LPV model, frequency domain framework.

Instrumental variable methods for closed-loop system identification

In this paper, several instrumental variable (IV) and instrumental variable-related methods for closed-loop system identification are considered and set in an extended IV framework. Extended IV methods require the appropriate choice of particular design variables, as the number and type of instrumental signals, data prefiltering and the choice of an appropriate norm of the extended IV-criterion...

Refined Instrumental Variable methods for closed-loop system identification

This paper describes optimal instrumental variable methods for identifying discretetime transfer function models when the system operates in closed-loop. Several noise models required for the design of optimal prefilters and instruments are analyzed and different approaches are developed according to whether the controller is known or not. Moreover, a new optimal refined instrumental variable t...

Computer-based Learning: What Automatic Speech Recognition Has to Offer

Virtual cities and landscape models – what has photogrammetry to offer?

The demand for geocoded (geographical, spatial) data will considerably grow for the next years. One driving force is the Internet, which allows the user to visit all spots on the Earth if their data is digitally stored and web-accessable. Another request for digital landscapes and city models comes from the communication technology to provide transmitters at the right spots and therefore to ove...
