Optimization Design of Magnetic Latching Relay Based on Hybrid Artificial Fish School Algorithm

A new kind of hybrid artificial fish school algorithm was applied to optimizing design of magnetic latching relay. In the initial optimization stage, the artificial fish school algorithm was used to obtain the stage optimum solution by its fast convergence ability. Then, based on the stage optimum solution, the genetic algorithm was introduced to obtain the global optimum solution by its good global extremum search ability. Consequently, the convergence rate and search accuracy had been improved significantly. The dynamic optimization calculation program of magnetic latching relay was designed and the optimization design example was showed. Finally, the results were validated by means of Adams. The experimental simulation results showed that the dynamic characteristics and the composite economic indicators of magnetic latching relay were improved.
