Abstract

On-board chargers within electric vehicles (EVs) must efficiently manage grid-to-vehicle (G2V), vehicle-to-grid (V2G), and vehicle-to-vehicle (V2V) modes for sustainable EV operation. This paper introduces a modified hybrid nonlinear control approach that utilizes the whale optimization algorithm-tuned supertwisted synergetic (WOA-ST-syn) technique for a multipurpose on-board charger (MP-OBC). The whale optimization algorithm(WOA) adjusts the parameters of supertwisted synergetic controller using the integral time absolute error, reducing the need for exhaustive trial-and-error adjustments. The controller employs the state space model of a two-stage on-board electric vehicle charging system, ensuring stability through the Lyapunov stability criterion. Simulations in MATLAB/Simulink evaluate the performance of the proposed controller across various operational modes, testing robustness against varying load currents and mode-switching conditions. Results indicate significant improvements over state-of-the-art nonlinear controllers, with minimal chattering, shortest rise time (0.0007 s for AC-DC, 1.5520 s for DC-DC), fastest settling time (0.0447 s for AC-DC, 2.0550 s for DC-DC), and minimal steady-state error (0.0010% for AC-DC, 0.0004% for DC-DC). Controller Hardware-in-the-Loop (C-HIL) experiments were also performed to confirm the real-time applicability of the controller.

针对电动汽车的 G2V/V2G/V2V 运行模式，对多功能车载充电器进行 WOA 调谐的超扭曲协同控制

电动汽车（EV）的车载充电器必须有效管理电网到车辆（G2V）、车辆到电网（V2G）和车辆到车辆（V2V）模式，以实现电动汽车的可持续运行。本文针对多功能车载充电器（MP-OBC）介绍了一种改进的混合非线性控制方法，该方法利用了鲸鱼优化算法调谐超扭曲协同（WOA-ST-syn）技术。鲸鱼优化算法（WOA）利用积分时间绝对误差来调整超扭曲协同控制器的参数，从而减少了反复试错调整的需要。控制器采用两级车载电动汽车充电系统的状态空间模型，通过 Lyapunov 稳定性准则确保稳定性。在 MATLAB/Simulink 中进行的仿真评估了拟议控制器在各种运行模式下的性能，测试了其在不同负载电流和模式切换条件下的稳健性。结果表明，与最先进的非线性控制器相比，该控制器的性能有了明显改善，颤振最小，上升时间最短（交流直流为 0.0007 秒，直流直流为 1.5520 秒），平稳时间最快（交流直流为 0.0447 秒，直流直流为 2.0550 秒），稳态误差最小（交流直流为 0.0010%，直流直流为 0.0004%）。还进行了控制器硬件在环 (C-HIL) 实验，以确认控制器的实时适用性。

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
