摘要:

针对具有有界过程和测量噪声的未知线性系统模型,提出了一种鲁棒数据驱动控制方案。提出了一种基于数据驱动可达区域的控制器,而不是传统预测控制中依赖于系统模型的控制器。数据驱动的可达区域是基于矩阵zonotope递归和计算的基础上,只有嘈杂的输入输出数据的轨迹的系统。我们假设测量和过程噪声包含在有界集合中。虽然我们假设这些界限的知识,没有关于噪声的统计特性的知识是假设的。在无噪声的情况下,我们证明了所提出的纯数据驱动的控制方案的结果在一个等效的闭环行为的名义模型预测控制计划。在测量和过程噪声的情况下,我们提出的方案保证了鲁棒的约束满足,这在安全关键应用中是必不可少的。数值实验表明,所提出的数据驱动控制器的有效性相比,基于模型的控制方案。

英文摘要:

We present a robust data-driven control scheme for an unknown linear system model with bounded process and measurement noise. Instead of depending on a system model in traditional predictive control, a controller utilizing data-driven reachable regions is proposed. The data-driven reachable regions are based on a matrix zonotope recursion and are computed based on only noisy input-output data of a trajectory of the system. We assume that measurement and process noise are contained in bounded sets. While we assume knowledge of these bounds, no knowledge about the statistical properties of the noise is assumed. In the noise-free case, we prove that the presented purely data-driven control scheme results in an equivalent closed-loop behavior to a nominal model predictive control scheme. In the case of measurement and process noise, our proposed scheme guarantees robust constraint satisfaction, which is essential in safety-critical applications. Numerical experiments show the effectiveness of the proposed data-driven controller in comparison to model-based control schemes.
