Towards reliable data-based optimal and predictive control using extended DMD

Manuel Schaller, Karl Worthmann, Friedrich Philipp, Sebastian Peitz, Feliks Nüske

摘要:

虽然Koopman为基础的技术,如扩展的动态模式分解是无处不在的数据驱动近似的动力系统,定量误差估计最近才建立。为此,必须考虑由有限字典和在代理模型的生成中仅有限多的数据点引起的误差源。我们概括的严格分析的近似误差的控制设置,同时减少维数灾难的影响,通过使用最近提出的双线性方法。特别是,我们建立统一的边界上的近似误差的状态相关的量,如约束或性能指标,使基于数据的最优和预测控制的保证。

英文摘要:

While Koopman-based techniques like extended Dynamic Mode Decomposition are nowadays ubiquitous in the data-driven approximation of dynamical systems, quantitative error estimates were only recently established. To this end, both sources of error resulting from a finite dictionary and only finitely-many data points in the generation of the surrogate model have to be taken into account. We generalize the rigorous analysis of the approximation error to the control setting while simultaneously reducing the impact of the curse of dimensionality by using a recently proposed bilinear approach. In particular, we establish uniform bounds on the approximation error of state-dependent quantities like constraints or a performance index enabling data-based optimal and predictive control with guarantees.
