基于滑模控制的感应耦合电能传输系统输出电压控制研究
Investigation of Output Voltage Control for the Inductive Power Transfer System Based on Sliding Mode Control Theory
摘要
Abstract
The power can be transferred from primary coil to secondary coil without direct contact using the inductive coupling power transfer system.It's difficult to design the system controller because of the change of load parameter,the complexity of the system structure and the higher operating frequency.A sliding mode controller based on Sliding Mode Control (SMC) theory is proposed to achieves the aim to control the output voltage via the phase-shift control strategy.This controller can dramatically improve the dynamic response performance of the system and it can reduce the dimension of the modelling method of traditional control systems.Firstly,the sliding mode controller is derived according to LCL-S based IPT system,and then the method of Sliding-mode coefficients selection is provided.Finally,the IPT experimental system is setup and tested under various conditions.The experimental results show that the sliding mode control has the characteristics such as faster dynamic response and less sensitive to the parameters mismatch,and better stability of the output voltage compared to the fine-tuned PI controller.关键词
