Study of magnetic actuation systems

This study presents an analysis of magnetic actuation systems (MAS). The behavior of an actuator is described by cross-coupled models of the mechanical and the electromagnetic interaction. The full MAS model is analyzed as a combination of four systems: electrical (power stage), control, mechanical and magnetic systems. In addition, the behavioral model that was developed, emulates the static and dynamic behavior of the actuator. The main benefit of the modeling approach is that it significantly reduces the complexity and burden in the design and control of multidisciplinary systems. An extended, non-linear inductor model has been developed, demonstrating the challenging control task of displacement regulation. The MAS model and the individual models have been demonstrated by simulations.
