摘　　要：针对无线电能传输系统(WPT)中,互感和负载的变化都可能对整个WPT系统性能造成影响这一问题,本文提出了一种改进麻雀搜索算法(SSA)的WPT系统参数识别方法。首先,建立了误差函数数学模型;然后,采用改进SSA对系统进行参数识别,将参数识别问题转化为参数寻优问题,得到参数识别结果;最后,搭建了WPT系统试验平台验证了识别方法的正确性。仿真与试验结果表明,该方法只需要发射侧电流采样数据即可快速有效地完成WPT系统互感与负载参数识别,根据识别结果调整移相角即可实现输出电压的恒定控制,仿真识别误差小于3%,试验识别误差小于5%。Aiming at the problem that mutual inductance and load changes in wireless power transmission systems(WPT)can affect the performance of the entire WPT system,an improved sparrow search algorithm(SSA)was proposed for parameter identification in WPT systems.First,the mathematical model of error function was established;Then,the improved SSA was used to identify the parameters of the system,transforming the parameter identification problem into a parameter optimization problem,and obtaining the parameter identification results;Finally,a WPT system experimental platform was built to verify correctness of the recognition method.The simulation and experimental results show that this method can quickly and effectively identify the mutual inductance and load parameters of the WPT system by simply sampling the current on the emission side.By adjusting the phase shift angle based on the identification results,constant control of the output voltage can be achieved.The simulation identification error is less than 3%,and the experimental identification error is less than 5%.
