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 ...
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 ...
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 ...
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 ...
Modern control design for a variable displacement hydraulic pump
(University of Missouri--Columbia, 2006)
In this work modern control methods are used to design and analyze control methods for a variable-displacement hydraulic pump. More accurate uncertainty descriptions are derived by using a structured uncertainty model as ...
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 ...
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 ...
