The research presented in this thesis relates to an actuation
and control concept whereby miniature hydraulic mechanisms
are sequenced by rotary spool valves. The objectives of the
work were to advance the technology, further develop the control
technique and improve the engineering of the associated hardware.
to enable the concept to be applied to high speed reciprocating
motions used in manipulative machinery. This necessitated
improved and predictable actuator and valve performance to overcome
deficiencies apparent in previous hardware. [Continues.]
