Investigation of Magnetic Force Hysteresis in Electromechanical Actuators

The practical implementation and parameterization of a model for estimating the magnetic force of valve solenoids involving a hysteresis model are evaluated. In a first step, popular approaches for modeling the force hysteresis of valve actuators are compared, followed by a description of the test bench used and the valve investigated. Next, the experimental procedure as well as the recorded data are described and discussed. Finally, a phenomenological modeling approach of force hysteresis is presented. The advantages and limitations are demonstrated and discussed using measured data.
