Abstract:

By developing some new analysis techniques, we show that the following feedback control system of differential equations with delays is permanent. dN(t)/dt = r(t)N(t)[1 - N-2(t - tau(1)(t))/k(2) (t) - c(t)u(t - tau(2)(t))], du(t)/dt = -a(t)u(t) + b(t)N(t - tau(1)(t)), tau(1), tau(2), a, b, c, r, k is an element of C(R, (0, +infinity)) are omega-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 fur Angewandt Mathematik und Mechanik 84 (6) (2004) 425-430].
