The existence of positive periodic solutions for periodic feedback control systems with delays
where τ, δ, a, b, c, r, k ∈ C(R, (0,∞)) are ω-periodic functions. The assumption of periodicity of the parameters a(t), b(t), c(t), k(t), r(t) is a way of incorporating the periodicity of the environment (e.g. seasonal effects of weather condition, food supplies, temperature, etc.). The main purpose of this paper is to establish the existence of a positive periodic solution of system (2), using...
متن کاملPeriodic Solutions of Nonlinear Dynamic Systems with Feedback Control
In this paper, sufficient criteria for the existence of multiple positive periodic solutions of a certain nonlinear dynamic system with feedback control are established. This is done by the Avery–Henderson fixed point theorem and the Leggett– Williams fixed point theorem. By using the method of coincidence degree, sufficient conditions are derived ensuring the existence of at least one periodic...
متن کاملPeriodic Solutions Design for Feedback Bilinear Systems
In this paper, we propose a feedback control for a class of bilinear systems. Based on the Bellman-Gronwall inequality, the exponentially stable periodic solutions or limit cycles, appearing as an ellipsoid in the phase plane, are guaranteed. Moreover, the frequency of oscillation and convergence rate can be correctly estimated for such bilinear control systems. Finally, a numerical example is ...
متن کاملExistence of Periodic Solutions for the Lotka-volterra Type Systems
In this paper we prove the existence of non-stationary periodic solutions of delay Lotka-Volterra equations. In the proofs we use the S-degree due to Dylawerski et al. [2].
متن کاملPeriodic solution for a delay nonlinear population equation with feedback control and periodic external source
In this paper, sufficient conditions are investigated for the existence of periodic (not necessarily positive) solutions for nonlinear several time delay population system with feedback control. Nonlinear system affected by an periodic external source is studied. Existence of a control variable provides the extension of some previous results obtained in other studies. We give a illustrative e...
