K. Balachandran et Jp. Dauer, NULL CONTROLLABILITY OF NONLINEAR INFINITE DELAY SYSTEMS WITH TIME-VARYING MULTIPLE DELAYS IN CONTROL, Applied mathematics letters, 9(3), 1996, pp. 115-121
Sufficient conditions for the null controllability of a nonlinear infi
nite delay system with time varying multiple delays in the control are
developed. Namely, if the uncontrolled system is uniformly asymptotic
ally stable, and if the linear system is controllable, then the nonlin
ear infinite delay system is null controllable.
