Wireless power transmission control method and device based on AE algorithm

Abstract

The invention belongs to the technical field of wireless power transmission, and discloses a wireless power transmission control method and device based on an AE algorithm, and the method comprises the steps: constructing a BP neural network according to the requirements of a wireless power transmission system for the stable control of a secondary voltage; obtaining an initial candidate solution population with a plurality of candidate weight vectors Xi through random initialization; a BP neural network outputs a correction amount for correcting a PID parameter through forward propagation according to an error signal collected in real time and historical information thereof, and after the correction signal and PID control output are superposed, a wireless power transmission system is driven, so that the secondary voltage is stable. According to the method, the global search capability of the initial weight of the network is improved, and the system is ensured to still have better adaptive performance under complex nonlinear conditions, so that the technical problem of lower efficiency and stability in a wireless power transmission system is solved.
