Optimization of an Electromagnetic Linear Actuator Operating in Error Actuated Control System

In the paper an algorithm and computer software for the optimisation of error actuated control systems containing of an electromagnetic linear actuator is presented. The software consists of two main parts: (a) optimisation solver and (b) numerical model of the actuator. For the optimisation, the genetic algorithm (GA) has been used. The field discrete mathematical description is employed. The field-circuit model of the electromagnetic actuator includes: (a) the equation of a transient electromagnetic field, (b) equations which describe electric circuits of the system, including feedback, (c) the equation of mechanical motion and (d) the equation describing and the proportional-plus-integral-plus-derivative (PID) controller.
