摘　　要：本文针对感应电能传输系统分岔频率的输送控制问题,提出一种基于延时干扰的变轨控制方法.该方法在反馈控制环节中加入一段延时干扰,通过调节延时参数,可使系统相轨迹流在各稳定极限环吸引子间自由切换.文中以原副边均为串联谐振的感应电能传输系统为例,对该方法的机理及实现方案进行了研究,并通过仿真和实验验证了其有效性.论文的研究结果对类似多吸引子分岔行为的输送控制可提供一定的理论参考.Frequency bifurcation is the most typical nonlinear phenomenon in inductive power transfer （IPT） systems. Two stable and one unstable resonant frequencies exist in a bifurcated IPT system while the unstable one lies between the two stable frequencies. To achieve the transition control of the bifurcated frequencies, this paper proposes an orbit shift method through a time delay perturbation, which is applied to the feedback signal. The phase trajectory can be shifted among the stable limit cycle attractors by adjusting the parameters of the time delay perturbation. The operation principle and implementation of the proposed method have been investigated in detail on an example IPT system with series tuned primary and secondary circuits. Both simulation and experimental results have verified the validation of the proposed method. The research results can provide useful theoretical reference for transition control of other similar multiple-attractor bifurcation behaviors.
