    Abstract : The Rational Covariance Extension Problem is a problemin applied mathematics where one tries to find a rational spectral density thatmatches a finite covariance sequence. Applications of this can be used in areaslike speech- and image-processing. READ MORE

  3. 2. Autonomus Helicopter Landing on a Mobile Platform.

    University essay from KTH/Optimeringslära och systemteori

    Author : Rasmus Hansén; Axel Ringh; Victoria Svedberg; Nils Landin; [2011]
    Keywords : ;

    Abstract : In this thesis we investigate the problem of landing a helicopter autonomously on a mobile platform by designing controllers for the attitude- and translational dynamics in parallel. A mathematical model of the helicopter, in form of general 6-degrees-of-freedom rigid-body dynamics with application-specific actuations, is developed. READ MORE
