Observer Based l1 Robust Fault Detection
基于观测器的l1鲁棒故障检测方法

Based on the factorization of control systemoutput observer, a new robust fault detection strategy has been presented by using the l1 optimization theory. The l1 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.
