Sliding Mode Control for Electrohydrostatic Actuator

Sliding Mode Control for Electrohydrostatic Actuator

Electrohydrostatic actuator (EHA) is a new actuator for next generation aircraft actuation system. This actuator is essentially a nonlinear system; response speed and accuracy are the main consideration. We use sliding mode control for this nonlinear system in this paper. The variable structure filt...
