摘要：

针对非接触电能传输系统的频率分叉问题,提出一种改进的参数设计方法.将频率分叉参数模型等效为约束条件,以传输效率最高为目标,同时考虑输出稳压、参数额定值等条件,建立系统的非线性规划模型,采用遗传算法来优化模型参数.为了增强算法处理约束的能力,去掉对约束的整体归一化以增大约束的整体权重|对没有可行个体的种群,将核心约束的满足比例作为新的自适应罚参数,以降低违反核心约束个体的适应度.仿真与实验结果表明：该算法处理约束能力增强|所得参数能使系统稳定运行于零相角频率处,无分叉现象|发现系统在频率分叉区外仍可能存在频率稳定的区域,降低系统参数优化的约束强度.
Abstract:

Aimed at the frequency bifurcation problem in contactless power transfer system, an improved method was proposed in parameter design. Frequency bifurcation parameter model was equivalent to constraints, the objective function was the transfer efficiency, taking into account the output voltage regulation, rating parameters and other conditions, a nonlinear programming model was created, and genetic algorithm (GA) was used to optimize the model parameters. An adaptive penalty function method was modified in order to enhance GA ability to deal with constraints, the overall constraint normalization was removed to improve the overall constraint weight and feasibility rate of the core constraint was made as a new adaptive penalty function for population without feasible individuals to reduce the fitness which violated core constraint. Simulation and experiment results show that, GA ability to deal with constraints is improved|System can be kept stable when running at zero-phase-angle frequency with no bifurcation. Its found that the system frequency may be kept stable in frequency bifurcation region so the traditional idea that determines the system frequency stability by frequency bifurcation point can be broken, and the constraint intensity of parameter optimization can be reduced.
