Titre : Minimum-time/energy, output transitions for dual-stage systems Type de document : texte imprimé Auteurs : Dhanakorn Iamratanakul, Auteur ; Devasia, Santosh, Auteur Année de publication : 2009 Article en page(s) : 08 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : dynamics (mechanics)  equilibrium (physics)  actuators  design  boundary-value problems  equations  polynomials Résumé : This article addresses the optimal (minimum-time/energy) trajectory design for changing the output from one value y̱ to another y¯ within a finite time interval [0,tf] called the output-transition time interval. The output should be maintained constant (at the desired value) outside the output-transition time interval. The main contribution of this article is to establish the existence of a solution to the problem when preactuation (input applied during time ttf) are allowed. The advantage of using pre- and postactuation inputs is illustrated with an experimental dual-stage actuator system.
