Design of power interface and its control strategy in hardware in the loop
摘要
Abstract
As interconnecting means that connected the physical side and the digital simulation side in hardware in the loop, the power interface plays a decisive role for the stability and accuracy of hybrid simulation system;so the design of power interface and its control strategy is a key for hardware in the loop.The DC voltage fluctuation caused by load power mutation and amplitude error in the power amplification process is the two main factors of the power interface stability and accuracy.Based on hardware in the loop, this paper designs its power interface and puts forward the four-quadrant back-to-back converter power interface device based on three single-phase H-bridge configuration.On this basis, considering the stability and accuracy of the power interface, the study of its control strategy is employed.In order to ensure good dynamic performance and DC voltage stable of power interface, a DC voltage optimum control strategy based on current feed-forward control is proposed.Considering the accuracy and stability of signal amplification, a composite control based on repetitive control for the inverter is proposed.Finally, the hardware in the loop tests verify the effectiveness of the proposed power interface and its control strategy.关键词
