Necessary and sufficient conditions for the quadratic stability and stabilization of such time-varying systems are derived. All the results are obtained in terms of linear matrix inequalities. Two illustrative examples are given to show that our results are effective and less conservative than the ...
this study provides additional insights into the identification of synergic interactions to accomplish the entrapment and motion of water droplets through a continuous hydrophobic phase, thus preventing the formation of locally disordered regions at the boundary of touching droplet islands and yielding full...
