中文摘要 |
针对电动汽车的模块化充电系统, 本文提出一种自适应预定性能控制器, 以解决负载变化引起的电压突变问题. 首先,引入障碍Lyapunov函数并结合反步法设计控制器, 以确保系统的输出电压能够限制在设定范围内; 其次,考虑电动汽车接入和离开时负载的变化情况,设计了一个有限时间负载估计器来估计负载的变化, 给出了输出电压有界及稳定性的严格证明; 最后,通过与传统PID和有限时间控制器对比, 验证了所设计控制器的有效性. |
英文摘要 |
In this paper, a predetermined performance controller is proposed for a modular charging system for electric vehicles to solve the problem of sudden voltage changes caused by changes in the load. Firstly, a barrier Lyapunov function is introduced and combined with the backstepping method to design the controller to ensure that the output voltage of the system can be limited to a set range. Secondly, consider the load changes when the electric vehicle is connected and left, a finite time load estimator is designed to estimate the load variation. A rigorous proof of bounded output voltage and stability is given. Finally, the effectiveness of the designed controller is verified by comparison with conventional PID and finite-time controllers. |
