1. 1. On the stability and control of piecewise-smooth dynamical systems with impacts and friction

   Författare :Fredrik Svahn; Annika Stensson Trigell; Harry Dankowicz; Jenny Jerrelind; Lawrie Virgin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-smooth dynamics; nonlinear control; low-velocity impacts; friction; bifurcations; Solid mechanics; Fastkroppsmekanik;

   Sammanfattning : This thesis concerns the analysis of dynamical systems suitable to be modelled by piecewise-smooth differential equations. In such systems the continuous-in-time dynamics is interrupted by discrete-in-time jumps in the state or governing equations of motion. LÄS MER

3. 2. Low-cost control of discontinuous systems including impacts and friction

   Författare :Fredrik Svahn; Annika Stensson Trigell; Harry Dankowicz; Jenny Jerrelind; Remco Leine; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear dynamics; discontinuities; nonlinear control; impacts; friction; vehicle suspensions; Vehicle engineering; Farkostteknik;

   Sammanfattning : For a successful design of an engineering system it is essential to pay careful attention to its dynamic response. This is particularly true, in the case of nonlinear systems, since they can exhibit very complex dynamic behaviour, including multiple co-existing stable solutions and chaotic motions, characterized by large sensitivity to initial conditions.
