A Digital Twin Based Real-Time Parameter Identification for Mutual Inductance and Load of Wireless Power Transfer Systems

The transmitter and receiver for wireless power transfer (WPT) need information interaction to achieve optimal efficiency if the mutual inductance load are movable. This paper proposes a parameter estimation system based on digital-twin concept aiming condition monitoring of WPT. digital replica physical experimental demonstrate an application series-series WPT system. A hybrid optimization algorithm Particle Swarm Optimization Simulated Annealing (PSO-SA) is applied estimate voltage current transmitting coil from both twin prototype. Compared with conventional methods, real-time, without auxiliary circuits invasion. In validation experiment, estimated parameters fit well actual values, verifying accuracy proposed approach in comprehensively describing state receiver. outcomes this study serve as critical step achieving noncommunication, cost-effectiveness, control
