Servo analysis by the ritz-galerkin method
Katsuhiko Ogata, C. P. Atkinson · Electrical Engineering · 1958
A THEORETICAL INVESTIGATION of a second order servomechanism with backlash was recently conducted. In the absence of a driving force, such a system may exhibit hunting phenomena in which the system oscillates with a certain amplitude and frequency. The Ritz-Galerkin method has been used for finding the hunting frequency and hunting amplitude of such a system. Theoretical results which were developed were found to agree with experimental results obtained by means of an electronic analog computer.
