数据驱动控制中动态模式分解预测精度的表征

Characterizing the Predictive Accuracy of Dynamic Mode Decomposition for Data-Driven Control

Qiugang Lu, Sungho Shin, Victor M. Zavala

摘要:

动态模式分解(DMD)是一种通用的方法,可以从数据中构建低阶模型。基于这种模型的控制器设计任务需要估计和保证预测精度。在这项工作中,我们提供了一个DMD模型误差的理论分析,揭示了模型阶数和数据可用性的影响。分析还建立了DMD模型可以渐近精确的条件。我们使用一个二维扩散系统验证我们的结果。

英文摘要:

Dynamic mode decomposition (DMD) is a versatile approach that enables the construction of low-order models from data. Controller design tasks based on such models require estimates and guarantees on predictive accuracy. In this work, we provide a theoretical analysis of DMD model errors that reveals impact of model order and data availability. The analysis also establishes conditions under which DMD models can be made asymptotically exact. We verify our results using a 2D diffusion system.
