This paper considers the impact of load variation on the “front-end” converter of cascade Point of Load (PoL) power electronic systems. With the assistance of real-time system identification, the parameters of Point of Load converter are obtained. A new dual feedback adaptive control strategy is then proposed, whereby the duty cycle of the “front-end” converter is carefully regulated to achieve the...
Time varying parameters, such of passive components within the circuit and load elements, can significantly impact on the control and voltage regulation of power electronic systems, such as switch mode power converters (SMPC). Therefore, there is increasing interest in parametric system identification and adaptive control techniques to optimize system performance. Most literature focuses on the DC-DC...
In this study, a framework is proposed for battery model identification to be applied in electric vehicle energy storage systems. The main advantage of the proposed approach is having capability to handle different battery chemistries. Two case studies are investigated: nickel-metal hydride (NiMH), which is a mature battery technology, and Lithium-Sulphur (Li-S), a promising next-generation technology...
