: Inductive coupled power transfer (ICPT) systems are now more desired to provide constant output voltage with the highest efficiency, which will be affected by source (input voltage) and load (load resistance) conditions. To address this issue, an integrated control method is proposed in this study, which is realised by using the active impedance matching technology based on the buck -boost circuit on the load side and the robust H ∞ control technology on the inverter side. This control scheme allows both two technologies to be applied simultaneously and independently operated. The bilateral inductor -capacitor inductor ICPT compensation system is used here to test the proposed method, which is representative, and it is also applicable to other typical compensation topologies and has a certain universality. Finally, an experimental platform is established. Experimental results show that the system can achieve 24 V constant output voltage and 84.53% efficiency tracking under the condition of simultaneous 20% input voltage disturbance and 50% load change, which shows the effectiveness of the proposed integrated control method.
