Dynamic output feedback control for wireless power transfer systems

Dynamic output feedback control for wireless power transfer systems This article investigates the control problem for the wireless power transfer (WPT) system, which has the characteristics of nonlinearity, high order, and associativity. Initially, a dynamic output feedback controller based on the WPT system is designed and analyzed. This controller can effectively enhance the stability of the system with stochastic disturbance. Besides, it does not need the knowledge of the system state in detail and has more adjustable parameters. Further, based on the Lyapunov theorem and stochastic stability theorem, a new stability result of the WPT with DOFC is obtained. In the stability results, all the variables in the system are still preserved after inequality expansion and contraction. Finally, the simulation results expound the effectiveness of the designed control scheme. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Asian Journal of Control Wiley

Abstract

This article investigates the control problem for the wireless power transfer (WPT) system, which has the characteristics of nonlinearity, high order, and associativity. Initially, a dynamic output feedback controller based on the WPT system is designed and analyzed. This controller can effectively enhance the stability of the system with stochastic disturbance. Besides, it does not need the knowledge of the system state in detail and has more adjustable parameters. Further, based on the Lyapunov theorem and stochastic stability theorem, a new stability result of the WPT with DOFC is obtained. In the stability results, all the variables in the system are still preserved after inequality expansion and contraction. Finally, the simulation results expound the effectiveness of the designed control scheme.
