Pulse Control of Single-Degree-of-Freedom System

The feasibility of using open-loop on-line adaptive pulse control to limit the vibrations of structural and mechanical systems, which are subjected to dynamic load environments, is investigated. The control algorithm is developed for a system modeled as a single degree of freedom oscillator. The technique while capable of adequate control for both linear and nonlinear systems subjected to stochastic loads, requires, unlike optimal control theoretic methods, a minimal amount of online computations to be performed. Results for linear time-invariant and time-variant as well as nonlinear systems are presented.
