Driven by the increasing needs in the process industry for designing fault-tolerant control systems based on process data and maintaining its performance during online operation, data-driven realization and design of feed-forward fault-tolerant control systems with embedded residual generation are studied. To this end, a parameterized and data-driven realization form of stable image representation in a feedback control loop is derived first. On this basis, a feed-forward controller design scheme is proposed for fault-tolerant purpose. It is followed by a recursive approach for online tuning the feed-forward controller in case of malfunctions, which is triggered by a fault detection scheme based on the so-called stable kernel representation. The effectiveness of the proposed fault-tolerant method is demonstrated by a case study on the laboratory three-tank system.

基于递归稳定图像表示的容错控制系统数据驱动设计
在过程工业中越来越需要基于过程数据设计容错控制系统并在在线操作过程中保持其性能的驱动下,研究了数据驱动的实现和嵌入式残差生成的前馈容错控制系统的设计。为此,首先导出在反馈控制回路中稳定图像表示的参数化和数据驱动的实现形式。在此基础上,提出了一种用于容错目的的前馈控制器设计方案。随后是用于在故障情况下在线调整前馈控制器的递归方法,该方法由基于所谓的稳定内核表示的故障检测方案触发。
