Dynamical analysis of the Irving-Mullineux oscillator equation of fractional order
Özet
Objective: Objective of this work is to study the fractional counterpart of the Irving-Mullineux nonlinear oscillator equation and compare the result with the integer order equation theoretically as well as numerically. Methods: For analytical results we use contraction principle to show the existence of the solution and then eigenvalue analysis to check the stability of the equilibrium points. Adams-type predictor-corrector method has been used for the numerical simulation. Results: Stability conditions are given in terms of the parameter epsilon. Numerical simulations indicate that the fractional differential equation shows stable result compared to their integer counterpart. Conclusion: The obtained results shown that the stability depends on the parameters and numerical results indicate that the fractional system may stabilize the corresponding integer order system. The results obtained also show that when alpha -> 1, the solutions of fractional equation reduce to the solution of corresponding integer equation. (C) 2014 Elsevier B.V. All rights reserved.
