摘要：
A fuzzy logic-integrated directional full-range tuning controller (DTC) for the output voltage regulation of a contactless parallel-tuned inductor-capacitor (LC) power pickup by switching the parallel tuning capacitor of the pickup circuit to make the equivalent tuning capacitance variable has been explained. Unlike the classical DTC that varies the equivalent tuning capacitance by a fixed step-size through trial and error approach, the proposed controller uses fuzzy-based reasoning to automatically select the tuning step-size for the DTC. The effectiveness of the proposed power pickup control method and its applicability to general wireless power transfer applications under variations in magnetic coupling, circuit tuning and the load has been verified by both simulation and experimental results. The controller can effectively reduce the output voltage chattering and steady-state error with faster response compared with the classical directional tuning controller.
