Abstract
A refined mathematical model of a direct current electromagnet has been developed, which takes into account the invariance of the direction and the quadratic dependence of the force on the magnetic flux and the gap. A simulation model of an electromagnet was built in the Matlab package. The structural instability of an unregulated electromagnetic suspension system is shown. A modal regulator that provides stability and specified quality indicators of static and dynamic modes has been synthesized. To simplify the technical implementation, a speed observer was developed. Comparative modeling of an electromagnetic suspension system was carried out when testing the reference influence and disturbances in force and working gap. The obtained research results confirm the developed model's performance and suitability for refined modeling and synthesis of electromagnetic suspension control laws, as well as evidence of the possibility of applying modal control and state observation methods for structurally unstable objects.
