A System of Degree Four with an Invariant Triangle and at Least Three Small Amplitude Limit Cycles
We show the existence of a polynomial system of degree four having three real invariant straight lines forming a triangle with at least three small amplitude limit cycles in the interior. Also, we obtain the necessary and sufficient conditions for the critical point at the interior of the bounded region to be a center.
متن کاملDesign and Implementation of a Control System for a DC Servomechanism with an Internal Dither Created by a Limit Cycle
Purpose of this paper is designing of a positional angle control system for a DC servomechanism. The servomechanism system consists of a direct current (DC) motor, a motor driver, a measuring sensor, and a control board to adjust angular position. The motor in the servomechanism has a non-linear element called dead-zone. Presence of dead-zone causes the nonlinear behavior of system. Injecting a...
متن کاملRelationship between Sperm Parameters with Sperm Function Tests in Infertile Men with at Least One Failed Cycle after Intracytoplasmic Sperm Injection Cycle
Objective Imbalance between production of reactive oxygen species (ROS) and total antioxidant capacity in testis, epididymis, and seminal fluid can eventually lead to subfertility and infertility. Abnormal chromatin packaging, and DNA fragmentation is considered as the main underlying causes. In this regard, we aimed to assess relationship between sperm parameters with DNA damage, protamine def...
متن کاملLimit cycle analysis on a cubic Hamiltonian system with quintic perturbed terms
This paper intends to explore bifurcation behavior of limit cycles for a cubic Hamiltonian system with quintic perturbed terms using both qualitative analysis and numerical exploration. To obtain the maximum number of limit cycles, a quintic perturbed function with the form of R(x, y, λ) = S(x, y, λ) = mx2 + ny2 + ky4 − λ is added to a cubic Hamiltonian system, where m, n, k and λ are all varia...
متن کاملAn efficient method to control the amplitude of the limit cycle in satellite attitude control system
In this paper, an efficient method is presented to control the attitude of a satellite with ON-OFF actuator. The main objective of this novel method is to control the amplitude of the limit cycle which commonly appears in the steady state of such systems; and at the same time by consideration of real actuator constraints, reduce the fuel consumption of system. The Proposed method is a combinati...
