Sensitivity analysis and optimal design of conventional and magnnetorheological fluid brakes
(University of Missouri--Columbia, 2018)
Mechanical and electrical brakes have dominated the braking industry for many years and will most likely continue to do so for the foreseeable future due to their low cost and adequate operating performance, wide range of ...
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)
control methods that comprise modified PI control, LQG control, H [mobius] control, and nonlinear feedback control are used to make a closed-loop poppet system. The nonlinear controller is only applied to the nonlinear system and certified by Lyapunov...
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 ...
Using feedback linearization to alter the performance of multiple linear hydraulic-actuators powered by the same pump
(University of Missouri--Columbia, 2020)
-actuators with both actuators being powered by the same pump. This research uses two open-centered 4-way valves to control the displacement of the two hydraulic actuators for a wheel loader implement system, based upon an input command from the operator who is modeled...
