| 中文摘要 |
| 本文研究了事件触发传输机制下线性随机系统的传感器间歇故障检测问题. 首先, 基于非均匀采样的方法,将具有事件触发传输机制的系统转化为线性时变系统. 然后, 基于Kalman滤波理论设计了故障检测滤波器, 并给出了新的残差设计方法. 所设计残差同时解耦了触发误差与估计误差, 能够有效地检测出间歇故障的发生时刻与消失时刻. 进一步, 利用随机分析理论研究了间歇故障的可检测性. 最后, 数值仿真和实验结果验证了所得结论的有效性 |
| 英文摘要 |
| In this paper, the problem of sensor intermittent fault detection is investigated for linear stochastic systems under event-triggered transmission mechanism. Firstly, by means of the non-uniform sampling pattern, the event-triggered system is transformed into a linear time-varying system. Then, the fault detection filter is designed based on the Kalman filter theory, and a novel residual generator is proposed. The event-triggered transmission error and estimation error are simultaneously decoupled from residual signals, which can be utilized to detect the appearing time and disappearing time of the intermittent fault effectively. Moreover, the detectability of intermittent faults is analyzed by virtue of the stochastic analysis theory. Finally, the effectiveness of derived results is verified by the numerical example and experiment. |
