To improve the transmission efficiency and output power of a magnetically coupled resonant wireless energy system, this paper proposes multi-objective optimization method based on analytical expression improved NSGA-II algorithm. First, expressions electrical performance parameters in mechanism are derived. On basis, mathematical model is established, with size, many turns, wire diameter transm...

The association mechanism between the main operation parameters and multi-physical fields of large-scale vertical mill system is unclear, which leads to difficulty in optimizing improve performance large systems. To investigate field coupling mill, numerical simulation method constructed by coupled CFD-DPM model calculate finished product quality, results were good agreement with actual results...

In this paper, a novel multi-objective orthogonal simulated annealing algorithm MOOSA using a generalized Pareto-based scale-independent fitness function and multi-objective intelligent generation mechanism (MOIGM) is proposed to efficiently solve multi-objective optimization problems with large parameters. Instead of generate-and-test methods, MOIGM makes use of a systematic reasoning ability ...

fuzzy clustering methods are conveniently employed in constructing a fuzzy model of a system, but they need to tune some parameters. in this research, fcm is chosen for fuzzy clustering. parameters such as the number of clusters and the value of fuzzifier significantly influence the extent of generalization of the fuzzy model. these two parameters require tuning to reduce the overfitting in the...
