F. Bucci et L. Pandolfi, The regulator problem with indefinite quadratic cost for boundary control systems: the finite horizon case, SYST CONTR, 39(2), 2000, pp. 79-86
In this paper we study the finite horizon non-standard LQ-problem for an ab
stract dynamics, which models a large class of hyperbolic-like partial diff
erential equations. We provide necessary/sufficient conditions for finitene
ss of the value function corresponding to the control problem. Sharpness of
sufficient conditions is shown by means of counterexamples. The specific f
eatures of the finite, in contrast to infinite, horizon case are illustrate
