摘要: 研究了采样数据系统的故障检测问题.关键在于通过引入算子来分别描述连续时间的 未知输入信号和故障信号对离散时间的残差信号的影响,从而把鲁棒性和灵敏度问题定义为一 个优化问题,并给出了相应的解.仿真例子验证了该方法的有效性.Abstract: The fault detection problem in sampled-data systems is studied. The key point is to introduce operators to describe the influence of the continuous-time unknown input signal and fault signal on the discrete-time residual signal, respectively. Based on this, the robustness and sensitivity problem can be defined as an optimization problem and the corresponding solution is derived. The simulation results illustrate the effectiveness of the proposed approach.
