摘要：针对感应式电能传输(IPT)系统负载变化时,传输效率降低和输出电压波动的问题,提出一种最大效率追踪与改进自抗扰复合控制策略。首先,分析LCC-S型IPT系统传输特性,推导出传输效率与二次侧DC-DC电路占空比的关系。然后,通过一次侧Buck电路调节二次侧DC-DC电路的占空比,实现阻抗匹配,从而实现最大效率追踪控制。与此同时,为了提升IPT系统输出电压的动态调节能力,提出一种改进自抗扰控制器,通过对扩张状态观测器降阶并引入模型信息,提高扰动补偿效果,结合线性误差反馈律实现二次侧DC-DC电路恒压控制。最后,搭建IPT系统实验平台,实验结果表明:在宽负载变化工况下,IPT系统输出电压恒定,平均传输效率较未进行最大效率追踪提升12%。改进的控制器相比线性自抗扰控制(LADRC)技术,调节参数更少,在负载波动和参考电压突变下,响应速度优于PI和LADRC,电压波动更小。
To resolve reduced transmission efficiency and output voltage fluctuations in inductive power transfer(IPT)systems under load variations,a composite control strategy integrating maximum efficiency tracking with improved active disturbance rejection control was proposed.The transmission characteristics of the LCC-S IPT system were analyzed,and the relationship between transmission efficiency and the duty cycle of the secondary-side DC-DC circuit was derived.Impedance matching was then achieved by regulating this duty cycle through the primary-side Buck circuit,enabling maximum efficiency tracking control.Concurrently,to enhance dynamic voltage regulation,an improved active disturbance rejection control was designed by reducing the order of the extended state observer and incorporating model information,which strengthened disturbance compensation.Combined with a linear error feedback law,constant voltage control for the secondary-side DC-DC circuit was realized.An experimental IPT platform demonstrated that under wide load variations,the output voltage remained stable with a 12%average efficiency improvement over non-tracking systems.Compared with linear active disturbance rejection control(LADRC),the proposed controller requires fewer tuning parameters,delivers faster response under load fluctuations and reference voltage steps than PI/LADRC,and reduces voltage fluctuations.
