RISA Novel Nonlinear Modeling and Dynamic Analysis of Solenoid Actuated Butterfly Valves Coupled in Series
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we focus on a novel nonlinear modeling and dynamic analysis of the actuated butterfly valves coupled in series. The actuated valves used in the chilled water systems of the U.S. Navy and commercial ships, ...
Analytical and Experimental Decentralized Adaptive Control of a High-Degrees-of-Freedom Robot Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we study the analytical and experimental control of a seven degrees-of-freedom (7DOF) robot manipulator. A model-free decentralized adaptive control strategy is presented for the tracking control of the ...
On the Inclusion of Time Derivatives of State Variables for Parametric Model Order Reduction for a Beam on a Nonlinear Foundation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The computational burden of parameter exploration of nonlinear dynamical systems can become a costly exercise. A computationally efficient lower dimensional representation of a higher dimensional dynamical system is achieved ...
Chaotic and Hyperchaotic Dynamics of Smart Valves System Subject to a Sudden Contraction
Publisher: The American Society of Mechanical Engineers (ASME)
