Model reference adaptive control of axial piston pump
IOP Conference Series: Earth and Environmental ScienceAbstract The paper is devoted to synthesis and implementation of a model reference adaptive controller (MRAC) for real-time displacement volume regulation of an axial piston pump. The controller of the developed real-time system evaluates control signal values applied to the proportional spool valve.

Rocketdyne LOX bearing tester program [PDF]
The cause, or causes, for the Space Shuttle Main Engine ball wear were unknown, however, several mechanisms were suspected. Two testers were designed and built for operation in liquid oxygen to empirically gain insight into the problems and iterate ...
