Nonlinear optimal control of electro-hydraulic actuators
IFAC Journal of Systems and Control, 2021Abstract A nonlinear optimal (H-infinity) control approach is proposed for electro-hydraulic actuators. Control of electrohydraulic actuators is a non-trivial problem because of the nonlinearities and underactuation in their dynamics. The article’s approach relies first on approximate linearization of the state–space model of the electrohydraulic ...

Applications of electro-hydraulics actuators
SoutheastCon 2016, 2016Electro-hydraulic systems can be used in robust robotics systems that have to carry heavier loads efficiently. Electrical drives have proven to be reliable and easy to control, but they may have problems when it comes to holding a position under load for a long period of time.

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 ...
