摘要

以石油钻井装置中的电能无线传输技术应用为背景,针对宽温度范围下系统参数变化导致系统偏离软开关工作点,造成系统传输性能下降甚至无法工作的情况,通过实验分析研究,给出感应耦合电能传输（ICPT）系统主要参数随温度变化的规律;基于频闪映射建模方法和周期不动点理论对主电路进行建模分析,给出系统谐振频率随温度变化的关系,为调整驱动频率实现系统软开关控制提供依据;提出一种查表法和扰动观察法相结合的控制方法,实现了ICPT系统在宽温度范围下的软开关控制。最后,通过仿真和实验验证了所提理论和方案的可行性和有效性。

Abstract：

For applications of wireless power transfer (WPT) technologies in the oil drilling rig, this paper proposes the changing laws of the main parameters of ICPT system with the variety of temperature through experimental analysis. The changing laws contribute to solving the problem of operating frequency deviation from the soft switching point caused by the parameters drift in the wide temperature range, and help to prevent inductive coupled power transfer (ICPT) system from transmission performance reduction and breakdown. The model of the main circuit is established based on the stroboscopic map modeling method and the cycle of the fixed point theory. Besides, the relationship between the resonance frequency of the system and the temperature is obtained, which provides evidences for the regulation of the driving frequency to achieve the soft switching control. In addition, a method combined with look-up table method and disturbance observation is proposed to ensure that the ICPT system can realize the soft switching control over the wide temperature range. Finally, simulations and experiments have verified the feasibility and effectiveness of the theory and scheme.

Key words： Inductive coupled power transfer system soft switching wide temperature range disturbance observation method
