This study presents an innovative control method for a specific type of DC/DC power converter, known as a three-leg interleaved non-isolated converter (IBC), which is particularly useful for proton exchange membrane fuel cell (PEMFC) electric vehicles (EVs). The control strategy introduced is a dual-loop system, utilizing a fractional-order proportional-integral (FOPI) technique. This includes two components: an external loop for DC bus voltage regulation and an internal one for current control(control of the FC through their IBC). This approach aims to swiftly adjust to changes in load and disturbances while maintaining high-quality dynamic performance, even in open circuit faults (OCF) scenarios. The FOPI based-controller’s optimal parameters are meticulously determined through the Equilibrium Optimizer (EO) algorithm, enhancing overall system performance and responsiveness. Evaluation and comparison of the proposed controller’s efficiency and superior performance are conducted against formal FOPI and other optimization algorithms using Matlab-Simulink simulation software. Practical validation involves the implementation of the proposed controller on a laboratory prototype-a 1.2KW three-phase interleaved boost converter-controlled by a dSPACE 1104 accusation card. The method exhibits outstanding practical results across diverse tests, including load variations, steady and transient states, and OCF modes. This comprehensive study contributes valuable insights into the realm of DC/DC power converter control. |
