Improved NSGA-Ⅱ Multi-Objective Optimization Design of Eddy Current Repulsion Fast Operating Mechanism
A multi-objective optimization design method of improved NSGA-Ⅱ algorithm is proposed aiming at the distribution of optimal solution set of multi-parameter and multi-objective optimization design of eddy current repulsion operating mechanism for the low-voltage AC breaker.Firstly,the principle of eddy current repulsion operating mechanism is analyzed.of which the finite element analysis simulation model is established,Thus,the optimization objectives and optimization variables are determined according to the requirements of application.Secondly,the original crowding-distance ranking algorithm is replaced by cyclic crowding-distance ranking algorithm to improve the distribution of Pareto's optimal solution set.An adaptive strategy based on inverse trigonometric function is introduced to update the crossover and mutation probabilities to improve the adaptability of the algorithm.Finally,the current repulsion operating mechanism is optimized with multiple-objective by the improved NSGA-Ⅱ algorithm,which achieves good results with obtained optimal frontier of Pareto.
