摘要

本文针对厌氧消化工艺介绍了一种基于滑动模式控制（SMC）策略的稳健控制方法。我们使用厌氧消化模型 N°01 (ADM1)（最详细、最全面的厌氧消化模型）作为虚拟厌氧消化工厂。我们提出的控制方案源自简化模型。该控制法使用简化版 AM2HN 模型的状态变量以及化学计量和动力学参数。在闭环中设计了 ADM1 和 AM2HN 状态变量之间的接口块。低通滤波器的使用提高了 SMC 的性能，完全消除了颤振，提供了平稳的稀释率（无颤振），同时在嘈杂的环境中快速达到目标甲烷产量（不到 5 天）。

Robust methane production from anaerobic digestion of maize silage: Feeding control using sliding mode control strategy with Anaerobic Digestion Model N°01

This paper introduces a robust control approach based on the Sliding Mode Control (SMC) strategy for the Anaerobic Digestion (AD) process. The Anaerobic Digestion Model N°1 (ADM1), the most detailed and comprehensive model in this field, is used as a virtual AD plant. The proposed control scheme is derived from a reduced model. This control law utilizes the state variables of the reduced AM2HN model along with the stoichiometric and kinetic parameters. An interface block between the ADM1 and AM2HN state variables has been designed in a closed-loop configuration. The performance of SMC has been enhanced through the use of a low-pass filter, which completely eliminates chattering, providing smooth, chatter-free dilution rates while preserving the rapid convergence to target methane production (within less than 5 days) even in a noisy environment.
