A new pension control approach to observer-based fault detection systems intelligent designing

In this paper, the pension control approach to observer-based fault detection systems intelligent designing is discussed. Considering the L
₂
-gain of residual system, this paper deals the observer-based fault detection problem. By using of H
_∞
control theory, a linear matrix inequality approach to design fault detection observer is given. The residual generating observer is designed under the L
₂
gain performance index. A numerical example is used to illustrate the effectiveness of the proposed approach.
