Abstract: Use of Galerkin’s method for the approximate analysis of nonlinear lumped systems is considered. A numerical procedure for finding Galerkin solutions of initial value problems is developed and ...

Abstract: A novel closed-loop method of obtaining the frequency response of a physical system is presented. It is assumed that the physical system to be examined may be excited by a known sinusoidal ...

Abstract: A method is presented for the determination of ordinary differential equations to describe the performance of existing lumped-parameter, time-invariant, nonlinear physical systems. It is assumed ...

Abstract: In this paper sensitivity analysis techniques are applied to two aspects of the nonlinear system design problem: The modeling of nonlinear systems and the compensation of nonlinear systems. In ...

Abstract: This paper describes an experimental method of establishing an ordinary differential equation to represent, or describe, a nonlinear physical system. Each nonlinear function that appears in the ...
