摘　　要：为提高无线充电控制系统的稳定可靠性,采用磁耦合谐振式传输系统,提出了泰勒展开式改进非均匀分段计算的开平方算法,实现功率可控的双边控制策略。首先设计双路电流负反馈控制器,降低负载电阻RL和磁耦合系数K对稳定性的影响;再在发送线圈电流负反馈电路中,运用泰勒展开式非均匀算法。算法分析了均匀和非均匀分段的误差情况,当展开项数合理时,能减小被开方数中的x,降低误差。采用TMS320F28335DSP实验仿真验证了系统设计的正确性,传输效率大于91%,系统计算精度得到提高。In order to improve the stability and reliability of wireless charging control system,a magnetic coupling resonant transmission system is proposed,and the Taylor expansion improved square root algorithm of non-uniform piecewise calculation is proposed to realize the two-sided control strategy of power control.Firstly,a dual current negative feedback controller is designed to reduce the influence of load resistance RLand magnetic coupling coefficient K on the stability,then the Taylor expansion non-uniform algorithm is used in the negative feedback circuit of the sending coil.The algorithm analyzes the error of uniform and nonuniform segmentation,when the number of expansion items is reasonable,the x in the number of the square root can be reduced and the error can be reduced.TMS320F28335DSP is used to verify the correctness of the system design,the transmission efficiency is greater than 91%,and the calculation accuracy of the system is improved.
