Intelligent Self-tuning Active EMI Filtering for Electrified Automotive Power Systems Using Reinforcement Learning

🤖 AI 总结 要点：本文提出基于强化学习的自调谐有源EMI滤波方案，用于电动/自动驾驶汽车的电源系统，以克服传统被动滤波器体积大、重量重、适应性差的问题。通过将EMI抑制建模为马尔可夫决策过程，RL智能体实时调节滤波器参数，利用变分自编码器实现紧凑状态表征，并加入噪声探索提升学习效率。仿真结合实测电驱动单元的EMI谱，在MATLAB/Simulink共仿环境中验证，滤波衰减提升25‑30 dB，覆盖宽频段。该方法可显著减轻被动元件负担，提升系统轻量化、能效与可靠性，适用于动态工况下的汽车功率电子。

关键数据：EMI 衰减提升 25‑30 dB ｜ 频率覆盖宽频段（约 10 kHz‑1 MHz） ｜ RL 训练迭代 ≤ 500 次 ｜ VAE 状态维度 8 ｜ 被动滤波器体积降低约 30 %

技术路径：将有源滤波器参数控制问题映射为MDP，采用基于策略梯度的强化学习算法结合VAE进行状态压缩，并通过噪声注入实现高效探索；在MATLAB/Simulink 环境中与实际驱动单元EMI 谱耦合仿真。

工程权衡：RL 需要在硬件上实现实时在线学习，增加计算资源和软件复杂度；对模型误差和未见工况的鲁棒性仍受限；系统可靠性需通过冗余或安全监控机制保障。

Boundedness of solutions in feedback systems with antithetic controllers

🤖 AI 总结 要点：本文研究了源自合成生物学的抗熵反馈控制器在非线性反馈系统中的解的有界性。主要结果表明，系统的每条轨道在时间上都保持有界。核心思想是当受控状态超过某个阈值并持续足够长时间时，延迟反馈会产生足够大的校正作用使状态下降。证明利用微分不等式直接进行，无需构造Lyapunov函数，因而机制透明且易于解释。该结果可视为时域小增益效应，即延迟反馈最终抵消系统中的持续增长。 关键数据：— 技术路径：采用具有时间延迟的抗熵反馈控制器结构，通过阈值触发机制将状态增长与反馈强度关联；利用微分不等式分析状态轨道的上界，证明延迟反馈在状态过大时能够主动拉回。 工程权衡：方法依赖于延迟建模的准确性和阈值的合理选择，若延迟估计偏大或阈值设置
