摘　　要：感应耦合电能传输(Inductive coupled power transmission,ICPT)技术凭借其在可靠性与安全性等方面的优点,目前已被广泛应用于水下设备的供电系统当中。为了解决应用于水下设备的多次级ICPT系统在工作距离与次级数量变化时输出电压波动较大的问题,本文提出了一种基于自抗扰控制(Active disturbance rejection controller,ADRC)的初级侧稳压控制策略。该策略通过捕捉初级工作电流作为反馈信号,可在各次级无通讯与稳压模块的条件下维持系统输出电压的稳定。文章通过建立多次级ICPT系统电路模型分别对系统的硬件电路与控制流程进行了设计。基于Matlab/Simulink&Maxwell的联合仿真与三次级ICPT系统样机实验均验证了本文控制策略的合理性与可行性,实验结果同时证明了该策略与其它控制算法相比拥有更好的鲁棒性能与动态特性。Inductive coupled power transmission technology(ICPT)has been widely applied in the power supply system of underwater equipment due to its advantages in reliability and security.To avoid the obvious fluctuation of the output voltage of ICPT system with multi-receivers with the working distance and the secondary quantity changes,we proposed a primary-side control strategy based on the active disturbance rejection controller(ADRC).By capturing the primary-side current as feedback,the strategy can maintain a constant voltage output without any communication module or voltage stabilizing module.The hardware circuit and control flow of the power transfer system was designed,respectively,by establishing the circuit model of multi-receivers ICPT system.The simulation based on Matlab/Simulink&Maxwell and the experiment of third-receivers ICPT system provided the rationality and validity of the above theory.At the same time,experiment result proved that the control strategy has better robust performance and dynamic characteristics compared with other methods.
