Applying and analyzing robust modern control on uncertain hydraulic systems
(University of Missouri--Columbia, 2006)In this work modern robust control systems are designed and compared to standard techniques for a hydraulic implement system. The system includes an independent metering valve (IMV) and a variable displacement pump. The ... -
Galilean moon tour using simplified trajectory computational techniques
(University of Missouri--Columbia, 2006)It is desired to find a trajectory for a spacecraft that will capture into an orbit about Jupiter and then subsequently capture into an orbit about each of the Galilean moons. The two main variables are the mass ratio, ... -
Modeling, design and control of forced-feedback metering poppet valve system
(University of Missouri--Columbia, 2006)This research explores valve design, dynamic modeling, and techniques to achieve flow control for a forced-feedback metering poppet valve system. In particular, nonlinear and linear models of a forced feedback configuration ... -
A single-sided access simultaneous solution of acoustic wave speed and sample thickness for isotropic materials of plate-type geometry
(University of Missouri--Columbia, 2006)In ultrasonic nondestructive evaluation, acoustic waves are used to inspect and characterize materials. Two commonly measured parameters are material thickness and acoustic wave speed in the material. These parameters are ... -
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)The goal of this work is to develop mathematical models, stability criteria, and control designs for a two-stage poppet valve system with a simple back-side pipeline condition that may be used in a valve stack to create ... -
Theoretical and experimental investigation of oscillating heat pipes
(University of Missouri--Columbia, 2006)A mathematical model describing the oscillation characteristics of slug flow in a capillary tube is presented. The model considers the vapor bubble as the gas spring for the oscillating motions in a capillary tube including ... -
Torque ripple attenuation for an axial piston swash plate type hydrostatic pump: noise considerations
(University of Missouri--Columbia, 2006)The main goal of this work is to reduce the disturbing noise generated by axial piston swash plate type hydrostatic pumps by attenuating the shaft torque variation. The analysis begins by deriving the equation of the shaft ...
