A review on the describing function calculation of double-valued characteristics. The inverse problem†
C. A. KARYBAKAS · International Journal of Control · 1973
A review on the method for the calculation of the describing function of double valued characteristics is presented here with extension to the inverse describing function problem. With this method the calculation of the DF of a characteristic is obtained by considering the function of the characteristic alone without the need of expanding the output waveform into Fourier series. In addition the method Leads to analytical forms from which the inverse problem, of finding special characteristics from their given describing functions, can be solved.
