RISA Dynamic Model of a Pressure Swing Oxygen Generation System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A full system model for oxygen generation from a pressure swing adsorption process is developed. The system under study has two zeolite packed molecular sieve beds which are cycled with high ...
Constitutive and Modulation Structure in Bond Graph Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigate additional structure that might be put on bond graphs in order that (1) a bond graph has a physical realization and (2) physical realizations have bond graph ...
Application of Nonlinear Quadratic Stochastic Control to a Position Servomechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear Quadratic Stochastic control is applied to a position servomechanism. A method for estimating the maximum sampling time of a digital implementation of the technique is given. Additionally, ...
A Dynamic Model of a Concentric LADD Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A LADD actuator is a device capable of converting rotational motion to translational motion and has potential for use in manipulators, robotics, and prosthetics. Two low order lumped parameter ...
Improved Statistical Linearization for Analysis and Control of Nonlinear Stochastic Systems: Part II: Application to Control System Design
