Szukana fraza: [Abstract = "With reference to the work of Verriest and Lewis \(1991\) on continuous finite\-dimensional systems, the linear quadratic minimum\-time problem is considered for discrete distributed systems and discrete distributed time delay systems. We treat the problem in two variants, with fixed and free end points. We consider a cost functional J which includes time, energy and precision terms, and then we investigate the optimal pair \(N, u\) which minimizes J."]
