论文摘要
在本文中，我们研究了由多个均质组件（例如并行处理机）组成的系统的容忍控制。与具有单个组件的系统相比，这种类型的系统通常更适合不确定性。每个组件的状态处于操作模式或故障。在任何时候，根据Bernoulli概率分布，每个组件可能会独立出现故障。如果组件有故障，则一直保持原状，直到固定为止。目的是通过顺序选择以下三个选项之一来设计容忍故障的系统：（a）不以零成本执行任何操作； b）以检查成本检测有故障组件的数量，c）以修复故障组件的成本来修复系统。开发了一个钟声方程来确定问题的近乎最佳解决方案。通过数值模拟验证了所提出的解决方案的功效。
In this paper, we study a fault-tolerant control for systems consisting of multiple homogeneous components such as parallel processing machines. This type of system is often more robust to uncertainty compared to those with a single component. The state of each component is either in the operating mode or faulty. At any time instant, each component may independently become faulty according to a Bernoulli probability distribution. If a component is faulty, it remains so until it is fixed. The objective is to design a fault-tolerant system by sequentially choosing one of the following three options: (a) do nothing at zero cost; b) detect the number of faulty components at the cost of inspection, and c) fix the system at the cost of repairing faulty components. A Bellman equation is developed to identify a near-optimal solution for the problem. The efficacy of the proposed solution is verified by numerical simulations.
