In this study, a novel integrated fault estimation (FE) and fault-tolerant control (FTC) design approach is developed for a system with time-varying delays and additive fault based on a dynamic event-triggered communication mechanism. The traditional static event-triggered mechanism is modified by adding an internal dynamic variable to increase the inter-event interval and decrease the amount of data transmission. Then, a dynamical observer is designed to estimate both the system state and the unknown fault signal simultaneously. A fault estimation-based FTC approach is then given to remove the effects generated by unknown actuator faults, which guarantees that the faulty closed-loop systems are asymptotical stable with a disturbance attenuation level γ. By theory analysis, the Zeno phenomenon is excluded in this study. Finally, a real aircraft engine example is provided to illustrate the feasibility of the proposed integrated FE and FTC method.

使用动态事件触发机制的线性时滞系统集成容错控制方法

在这项研究中，基于动态事件触发通信机制，为具有时变延迟和附加故障的系统开发了一种新颖的集成故障估计 (FE) 和容错控制 (FTC) 设计方法。修改了传统的静态事件触发机制，通过增加内部动态变量来增加事件间间隔，减少数据传输量。然后，设计了一个动态观测器来同时估计系统状态和未知故障信号。然后给出了一种基于故障估计的 FTC 方法来消除未知执行器故障产生的影响，这保证了故障闭环系统在干扰衰减水平为 γ 的情况下是渐近稳定的。通过理论分析，本研究排除芝诺现象。最后，
