Chapter 6Time-Delayed Nonlinear Oscillators

In this chapter, analytical solutions for period-m motions in a time-delayed, nonlinear oscillator will be presented through the Fourier series, and the stability and bifurcation analyses of the corresponding periodic motions are presented through the eigenvalue analysis. Analytical bifurcation trees of periodic motions to chaos will be presented through the frequency-amplitude curves. Trajectories and amplitude spectrums of periodic motions in such a time-delayed nonlinear system are illustrated numerically for a better understanding of time-delayed nonlinear dynamical systems.

6.1 Analytical Solutions

In this section, the analytical solutions of periodic motions in time-delayed, nonlinear systems will be developed through finite Fourier series. Consider a periodically forced, time-delayed, nonlinear oscillator as

where c06-math-0002 and c06-math-0003. Coefficients in Equation (6.1) are c06-math-0004 and c06-math-0005 for linear damping, and for linear springs and delay, and for quadratic ...
