This work considers the integration of interval operability analysis and fault-tolerant control design for non-square systems with actuator faults. First, a novel formulation of the virtual actuator based on a two-layer moving horizon approach is proposed. Then, in addition to the original concepts of interval operability, the explicit incorporation of fault effects considering the blocked positions of stuck actuators (lock-in-place) is presented. The proposed approach provides a systematic method to determine feasible operating ranges for output variables during fault scenarios. The interval operability assessment of actuator faults scenarios is performed in a two-CSTR system, resulting in operable and inoperable situations depending on the extent of the blocked actuator position.

这项工作考虑了具有执行器故障的非方形系统的区间可操作性分析和容错控制设计的集成。首先，提出了一种基于两层移动水平方法的虚拟致动器的新公式。然后，除了间隔可操作性的原始概念之外，还提出了考虑卡住执行器（锁定就位）的阻塞位置的故障影响的显式结合。所提出的方法提供了一种系统方法来确定故障情况下输出变量的可行操作范围。执行器故障场景的间隔可操作性评估在双 CSTR 系统中执行，根据阻塞执行器位置的程度导致可操作和不可操作情况。
