system, input current increased when load become lighter especially no-load
which led to system unstable. A method of frequency adjustment without adding
additional links was presented which could realize the control of input power.
The mathematical relationship between the input power and system operating frequency,
load resistance, input voltage in the voltage-fed ICPT system was built based
on mutual inductance theory. In order to improve the rapidity and accuracy of
the control method, the neural network control strategy which included control
network with three layers was added in the proposed method. Practical experiment
illustrated that the method could make the system with good robustness when
load changes in large scale. In instance, as the load resistance varied from
20-50 Ω, the input current returned to the reference value within a short
time which verified that the proposed control approach was effective for ICPT
system.]]>Boys, J.T., G.A. Covic and Y. Xu,200315153Hu, A.P.,20012001Li, Y.L., Y. Sun and X. Dai,201211971979Li, Y.L., Y. Sun and X. Dai,201360291300Si, P., A.P. Hu, S. Malpas and D.
