Stabilization strategy for unstable first order linear systems with large time‐delay

Abstract: This work considers the problem of stabilization of a class of unstable first order linear systems subject to a large input-output time delay. Necessary and sufficient conditions are stated to guarantee the stability of the closed loop delayed system by means of a compensation scheme based on two static gains and an induced delay term. The proof of the main result is derived by considering a discrete time approach that, under adequate assumptions, allows to conclude the stability condition for the continuous t… Show more

“…Then, there exist constants g 1 and g 2 such that the closed-loop system, is stable if and only if τ 2 < 2/a.■ Proof. The proof of this lemma is provided in Appendix A, and it is carried out as a slight modification of the one presented for a system of the form described in eq 1, 19 without considering the splitting strategy described by eq 4.…”

“…In many practical systems, however, time delays are ubiquitous and unavoidable. Because the existence of time delay may not only affect the performance of the control, but also even undermine the stability of a system [12][13][14][15][16][17][18][19][20], the influence of time delay for system performance can not be ignored. Switched nonlinear delay systems are often met in practical systems such as networked control systems, drilling systems, and mechanical rotational cutting processes [21][22][23].…”

“…This work was supported also by the development project of key laboratory of Liaoning Province. systems, the problem is relatively simple and general and effective techniques have been proposed mainly based on the Routh-Hurwitz criterion, such as, the Ziegler-Nichols method in [3], generalization of the Hermite-Biehler Theorem in [4], the Astrom-Hagglund method in [5], and also some new summary results in [6][7][8][9][10][11]. However, as inherent phenomena, time delays are encountered in a variety of interconnected real systems or processes, which makes the problem much more complex.…”
