... of both providing high flow when required and precise pressure control. This is realized with the balancing of the solenoid force and two fluid feedback volume forces. As a result, with high pressure difference during the clutch piston displacement, the spool is forced to the completely open position...

Another benefit of the simultaneous coordination of both control inputs is a reduction in the control effort required to elicit the desired response. Instead of using a peak pressure controller that must compensate for the effects of a combustion...

...Randall T. Anderson; Perry Y. Li A nonlinear dynamic model for an unconventional, commercially available electrohydraulic flow control servovalve is presented. The two stage valve differs from the conventional servovalve design in that: it uses a pressure control pilot stage; the boost stage uses...

Such valves are less expensive than typical servovalves but also tend to be limited in their dynamic performance. Based on a previously developed...
