• The describing function method, which is now extensively applied to the analysis of the nonlinear control system, neglects the constant component and all the higher harmonics in the Fourier expansion of the output from the nonlinear element and considers only its fundamental harmonic. Such an approximate method as this necessarily brings about more or less quantitative errors and is sometimes liable to committing fatal qualitative mistakes. Under these circumstances, the author has formerly devised a perfect Fourier series solution for the frequency response of the control system including a piecewise-linear element. In this paper, extending this line of approach one step further, the author takes up the self-excited vibration of a feedback control system including a simple backlash element, and shows that in this case higher harmonics play a decisive role in judging the stability of the system.
