Observer Based l ~1 Robust Fault Detection

基于参数化的控制系统输出观测器 ,将鲁棒控制理论中的l1最优化方法用于故障检测技术 ,提出一种新的控制系统鲁棒故障检测方法 .通过求解一个混合 0 1型整数线性规划问题 ,可得出l1优化残差函数 .

Based on the factorization of control system output observer, a new robust fault detection strategy has been presented by using the l 1 optimization theory. The l 1 optimal residual function can be obtained by solving a mixed 0 1 type integer linear programming problem. The validity of the new strategy was proved by simulation results.
