基于ADRC的LCC-S谐振型无线充电副边闭环控制研究
Research on Secondary-side Closed-loop Control of LCC-S Resonant Wireless Charging Based on ADRC
摘要
Abstract
Aimed at the problem that the output current and voltage from a magnetic coupling resonant LCC-S wireless charging system are easily affected by external disturbance or its own parameter disturbance during its working process,as well as the problem of how to respond to disturbances quickly and accurately,a secondary-side two-stage closed-loop control method of constant-current and constant-voltage based on active disturbance rejection control(ADRC)is proposed.First,the relationship between the output characteristics of LCC-S resonant network and system parameters is studied through the circuit analysis.Second,the state equation model of a secondary-side Buck converter is established to achieve the closed-loop precise regulation of system output,and the tracking differentiator,extended state observer and nonlinear state error feedback in ADRC are designed accordingly.Finally,an experimental platform of wireless charging based on ADRC was built.The control effect is compared between the ADRC and PI controllers under multi-parameter disturbance,and results show that the former shows a better dynamic regulation capability.关键词
