【摘要】：提出了一種基于最小二乘法的新型線圈自感辨識方法,以發(fā)射端和接收端電路串聯(lián)的電壓型無線能量傳輸(即充電)系統(tǒng)為例,建立其非線性高階微分方程并構(gòu)建數(shù)據(jù)矩陣,通過最小二乘法獲得系統(tǒng)的過程參數(shù)矢量,將線圈的自感辨識問題轉(zhuǎn)換為系統(tǒng)參數(shù)辨識問題,完成無線充電系統(tǒng)發(fā)射端和接收端線圈的自感辨識,最后通過仿真和實驗,驗證了該方法的可行性。
[Abstract]:A novel coil self-inductance identification method based on least square method is proposed in this paper. The nonlinear high-order differential equation and the data matrix of a voltage-type wireless energy transmission (charging) system connected in series between the transmitter and receiver are established. The process parameter vector of the system is obtained by the least square method, and the self-inductance identification problem of the coil is transformed into the system parameter identification problem. The self-inductance identification of the transmitter and receiver coils of the wireless charging system is completed. Finally, the simulation and experiment are carried out. The feasibility of the method is verified.
