stability and attraction domains of traffic equilibria in day-to-day dynamical system formulation

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...

Hopf Bifurcation of Maglev System with Coupled Elastic Guideway

In this paper, the dynamical behavior of single magnet suspension system of maglev train considering the elastic guide-way is researched through HOPF bifurcation theory. With three states feedback variables (gap, current, velocity), the HOPF bifurcation conditions and corresponding vibration frequency of the coupled system is presented under different flexible guideway conditions, that is, the ...

Bifurcation Control in Feedback Systems

In this chapter the mathematical tools from bifurcation theory are used within the framework of feedback control systems. The first part deals with a simple example where the amplitude of limit cycles and the appearance of period-doubling bifurcations are controlled using a method derived from the frequency domain approach. In the second part, bifurcation theory is used to analyze the dynamical...

Delayed Feedback Control and Bifurcation Analysis of an Autonomy System

and Applied Analysis 3 Lemma 2. For the polynomial equation (10), one has the following results. (i) If r < 0, then (10) has at least one positive root. (ii) If r ≥ 0 and 󳵻 = p − 3q ≤ 0, then (10) has no positive roots. (iii) If r ≥ 0 and󳵻 = p−3q > 0, then (10) has positive roots if and only if z 1 = (1/3)(−p +√󳵻) > 0 and h(z 1 ) ≤ 0. Suppose that (10) has positive roots, without loss of genera...
