摘要: |
设计了一款针对超级电容储能(Supercapacitor Energy Storage, SCES)系统的无源分数阶滑模控制(Passive Fractional-Order Sliding-Mode Control,PFOSMC)。首先,基于SCES系统固有的物理特性,构建储能函数并对其进行分析。随后,保留系统阻尼有益项以改进其动态响应,同时完全补偿系统阻尼无益项以实现全局一致的控制性能。最后,设计分数阶滑模控制(Fractional-Order Sliding-Mode Control, FOSMC)作为附加控制输入,旨在重塑系统能量使闭环系统严格无源,并引入分数阶比例-微分( )滑动平面以增强系统鲁棒性。仿真结果表明,PFOSMC的控制性能与PID控制、基于互联与阻尼配置的无源控制(Interconnection and Damping Assignment Passivity-Based Control, IDA-PBC)和FOSMC相比,其均可在各种工况下实现最好的动态响应和最高的鲁棒性。 |

Abstract: |
This paper designs a novel Passive Fractional-Order Sliding-Mode Control (PFOSMC) for a Supercapacitor Energy Storage (SCES) system. First, a storage function of SCES systems is developed in which inherent physical characteristics are thoroughly analyzed. Then, the beneficial terms are carefully retained to improve the dynamical responses of the SCES system, while the remaining detrimental terms are fully compensated for to achieve a global control consistency. Lastly, a Fractional-Order Sliding-Mode Control (FOSMC) framework is employed as an additional input to reshape the closed-loop system into an output of strictly passive form. At the same time a fractional-order sliding surface is designed to enhance system robustness. Simulation results verify that the PFOSMC can outperform the PID control, Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC), and FOSMC under different operational conditions.
