Aggressive Output Space-Mapping Optimization for Electromagnetic Actuators

Automated electromagnetic actuator design can be achieved by means of several approaches. For example, one might consider fast, however, accuracy deficient coarse models or, in contrast, the design could be achieved exclusively by employing accurate, time expensive, fine models. The space-mapping optimization technique, with its input or output mapping based implementations, merges the advantages of the two extremes. A new algorithm variant that presents a simple structure, namely the aggressive output space-mapping, is proposed in this paper. The design problem of a tubular permanent magnet actuator is considered in order to compare the proposed algorithm with two existing techniques.
