Electro-hydraulic actuator trajectory tracking
Proceedings of the 2004 American Control Conference, 2004This paper combines block control, sliding mode control and integral control techniques to design a controller, which is able to force an electrohydraulic actuator driven by a servovalve to track a given chaotic reference trajectory. This approach enables to compensate the inherent nonlinearities of the actuator and to reject external constant ...

Electro-hydraulic Servomechanisms†
Journal of Electronics and Control, 1958Abstract The additional complications of hydraulic elements have not prevented servomechanism engineers from resorting frequently in recent years to the use of high-pressure hydraulic motors in place of electric motors. The reasons for this trend are examined in relation to the performance demanded in many modern servomechanisms, particularly these in ...
