An active fault tolerant control (FTC) law is generally |
|
sensitive to false identification since the control gain |
|
is reconfigured for fault occurrence. In the conventional |
|
FTC law design procedure, dynamic variations due to false |
|
identification are not considered. In this paper, an FTC |
|
synthesis method is developed in order to consider |
|
possible variations of closed-loop dynamics under false |
|
identification into the control design procedure. An |
|
active FTC synthesis problem is formulated into an LMI |
|
optimization problem to minimize the upper bound of the |
|
induced-L2 norm which can represent the worst-case |
|
performance degradation due to false identification. The |
|
developed synthesis method is applied for control of the |
|
longitudinal motions of FASER (Free-flying Airplane for |
|
Subscale Experimental Research). The designed FTC law of |
|
the airplane is simulated for pitch angle command |
|
tracking under a false identification case. |
