Abstract: This paper concerns the wide class of physical networks made up of lumped components with transfer matrices whose elements are rational functions of the Laplace variables and hydraulic, pneumatic, ...

Abstract: The dashpot-type isochronous governor (which may be modified by droop) is the standard hydraulic governor in current use for prime movers. This governor is designed to give proportional-plus-integral ...

Abstract: A stability criterion for certain types of nonlinear feedback systems in the presence of Gaussian noise is established here. This criterion may be considered as a natural extension of the ...

Abstract: In many hydraulic control and other systems the effect of fluid carrying lines is an important factor in system dynamics. Following electrical transmission line technique a hydraulic line between ...

Abstract: This paper presents a method for finding necessary conditions such that a subharmonic oscillation may exist in certain types of nonlinear feedback systems. The method is applicable to feedback ...
