Abstract

We investigate the detection of limit cycles arising from Hopf bifurcation phenomena by applying the harmonic balance method with different higher order approximations. We present the results via an enlightening graphical procedure which indicates clearly how the predictions of amplitude and frequency of a periodic solution can be improved by using higher and higher order approximations. Moreover, we provide complete and explicit formulas for the eighth-order harmonic balance approximation.
