摘要
考虑了一类具有未知有界噪声的线性多输入多输出(MIMO)系统的故障检测问题,提出了一种基于集员估计的故障检测方法.通过当前时刻系统状态范围和测量输出值的一致性检验来检测系统是否发生故障.如果系统正常运行,则利用系统测量输出信息校正当前时刻系统状态范围.利用三容水箱系统模型进行了仿真研究,结果表明了所提方法的有效性.
The fault detection problem was investigated for a class of linear multiple-input multiple-output (MIMO) systems with bounded noise. A new fault detection method was proposed based on setmembership estimation. Consistency test was performed by the available present state range and measurements to determine whether there was a fault. If the system was in normal operation, the state range was corrected by taking advantage of the information provided by the measurements. A simulation study on the three-tank system was further carried out to demonstrate the effectiveness and applicability of the proposed method.
