In the paper an algorithm and computer software for the optimisation of error actuated control systems containing 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-circuit discrete mathematical model of the actuator has been employed. The model includes: (a) the equation of a transient electromagnetic field, (b) equations which describe electric circuit of the actuator, (c) the equation of mechanical motion and (d) the equation describing the feedback - including the proportional-plus-integral-plus-derivative (PID) controller.
