Abstract
A position reconstruction method for camless engine electromagnetic valve actuators control without direct position measurement is proposed. The method makes use of flux signals, obtained through integration of a secondary coil voltage added at each electromagnet. By this solution, both fluxes and position signals are available for the design of the feedback position controller. The paper discuss the accuracy that can be obtained for position reconstruction, linking it to the system parameters tolerances. Experimental results are reported to show the validity of the proposed solution.
