N2 - Electromechanical actuators are widely used in mechatronic systems where linear motion is desired. In shortstroke fast-motion applications such as variable valve control of internal combustion engines the electromagnetic actuator is often applied in combination with additional mechanical springs storing motion energy and making high force densities possible. However, the control of thoseelectromechanical systems under constraints of high dynamic, soft-landing, strongly changing disturbances and limited current is not an easy issue as the system to be controlled is non-linear. This paper deals with structural properties of the physical system like flatness. A flatness based approach is used to achieve a soft landing. In addition a geometric switching control strategy is proposed in order to reject the pressure disturbances by generating an invariant set. Real model parameters and measured data are used to validate the proposed approach and its feasibility by computer simulations.
