摘要
为改善开关磁阻发电机在中低速段的运行性能,提出了一种离线开关磁阻发电机控制参数优化方法。针对运行环境需求,将开关磁阻发电机的最大输出功率、系统效率和转矩平滑系数作为优化目标,分析了开通角、关断角、参考电流对各优化目标的影响,得出各单一目标优化下最优控制参数组合。然后构建了多目标优化目标函数,给出了各优化目标权重系数,得到了多目标优化下最优控制参数组合。最后样机实验表明,该文提出的多目标优化方法得出的控制参数组合能够有效改善开关磁阻发电机在中低速段的运行性能。
To improve the performance of switched reluctance generators at medium and low speeds, an off-line control parameters optimization method for switched reluctance generators is proposed in this paper. The maximum output power, the system efficiency and the torque smoothing coefficient are considered as the optimization objectives. The influences of turn-on angle, turn-off angle and reference current on each optimization objective are analyzed. The optimal control parameters of each single-objective optimization are obtained. Then, a multi-objective optimization function is determined with given weight coefficients to optimize control parameters. Finally, experimental results show that the optimal control parameters obtained by the proposed optimization method can improve the performance of switched reluctance generators at medium and low speeds.
