Abstract:

By developing some new analysis techniques, we show that the following feedback control system of differential equations with delays is permanent. frac(d N (t), d t) = r (t) N (t) [1 - frac(N2 (t - τ1 (t)), k2 (t)) - c (t) u (t - τ2 (t))],frac(d u (t), d t) = - a (t) u (t) + b (t) N (t - τ1 (t)), where τ1, τ2, a, b, c, r, k ∈ C (R, (0, + ∞)) are ω-periodic functions, which means that feedback control variable has no influence on the persistent property of the above system. Our result supplements the main result of Fan, Li and Qin [G.H. Fan, Y.K. Li, M.C. Qin, The existence of positive periodic solutions for periodic feedback control systems with delays, Zeitschrift für Angewandt Mathematik und Mechanik 84 (6) (2004) 425-430]. © 2009.
