Abstract :
An algorithm of coupled field-circuit simulation of the dynamics of an electromagnetic linear actuator operating in error actuated control system is presented. The software consists of three main parts: (a) numerical model of the actuator dynamics which includes equations of a transient electromagnetic field in a non-linear conducting and moving medium, (b) discrete model of electric circuit and (c) optimization solver. Numerical implementation is based on the finite elements. The influence of the PID controller settings on the actuator operation is shown. In order to find optimal parameters of the system the genetic algorithm is applied. The simultaneous optimization of both: actuator structure and regulator settings has been carried out.
