Modern control design for a variable displacement hydraulic pump
(University of Missouri--Columbia, 2006)
uncertainty model. The system studied includes one variable-displacement swash-plate hydraulic pump with a constant engine speed model. The input to the system is the current actuating the control valve position, while the system output is the discharge...
Design optimization and efficiency modeling of a hot gas vane motor
(University of Missouri--Columbia, 2007)
The purpose of this research is to model and analyze the dynamics of a hot gas vane motor for design optimization work. The pneumatic motor is a portable direct drive actuator that is intended as an alternative to ...
Force control of a hydraulic servo system
(University of Missouri--Columbia, 2009)
The objective of this thesis is to model a hydraulic servo system using force control and then improve upon the performance of the model/system through feedback control design. The hydraulic system is first constructed and ...
Investigation of the performance of an automatic arterial oxygen controller
(University of Missouri--Columbia, 2018)
Premature infants often require respiratory support with a varying concentration of the fraction of inspired oxygen (FiO2) to keep the arterial oxygen saturation (SpO2) within the desired range to avoid both hypoxemia and ...
Nonlinear control and active damping of a forced-feedback metering poppet valve
(University of Missouri--Columbia, 2007)
For a metering poppet valve which was developed at the University of Missouri (MU valve), the valve can be configured for performance at the cost of stability. It is desirable to achieve both performance and stability using ...
A method of frequency domain error modeling to predict the probability of stability and performance of dynamic systems with parametric uncertainty
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this work a method is developed for modeling frequency domain error in dynamic systems with parametric uncertainty. Within any mass-manufactured ...
Developing and automating time delay system stability analysis of dynamic systems using the Matrix Lambert W (MLW) function method
(University of Missouri--Columbia, 2009)
Stability analysis of time-delayed (TD) systems is not easy to conduct since the addition of delays within a dynamic model results in irrational system equations. Traditional TD analysis methods involve adding approximations ...
