Optimal control of electromagnetic actuator considering energy loss minimisation in electric circuit

A finite element - based simulation of the single - phase electromagnetic actuator control including 3D electromagnetic field, circuit and movement model coupling to optimal control is presented. The subject of this paper is to study an optimal control technique that minimises quadratic energy function in the electric circuit. As a new contribution an algorithm based on Linear Quadratic Problem coupled with electromagnetic actuator model in a closed - loop control system is proposed.
