Abstract

This paper presents a control concept for Electro-Magnetic Actuators (EMA) under the effect of strong and dynamic disturbances. The proposed control consists of two components, a backstepping control which exploits the knowledge of the plant and of a disturbance observer. Experiments at a test stand show that the presented approach is able to fulfill very high dynamic requirements and to reject disturbances with a higher dynamics than the actuator under realistic conditions.
