| 中文摘要 |
| 提出一种对采样数据系统进行故障检测的H∞方法. 首先构造离散时间故障检测系统, 分析残差产生器的动态特性. 然后从故障检测的角度引入算子, 定量考察连续时间未知输入信号和故障信号对离散时间残差信号的影响. 最后优化残差产生器的参数, 使得故障检测系统对未知输入具有较强的鲁棒性, 同时对故障具有较高的灵敏度. |
| 英文摘要 |
| An H-infinity, approach to fault detection in sampled-data systems is presented. At first a discrete-time fault detection system is constructed and the dynamics of the residual generator is analyzed. Then an operator is introduced from the viewpoint of fault detection to describe quantitatively the influence of the continuous-time unknown inputs and faults on the discrete-time residuals. Finally the parameter of the residual generator is optimized, so that the fault detection system is robust to the unknown inputs and simultaneously sensitive to the faults. |
