Abstract:
|
In this paper, a Fault Tolerant Control (FTC) strategy for Linear Parameter Varying (LPV) systems that can be used in
the case of actuator faults is proposed. The idea of this FTC method is to adapt the faulty plant instead of adapting the
controller to the faulty plant. This approach can be seen as a kind of virtual actuator. An integrated FTC design procedure
for the fault identification and fault-tolerant control schemes using LPV techniques is provided as well. Fault identification
is based on the use of an Unknown Input Observer (UIO). The FTC controller is implemented as a state feedback controller
and designed using polytopic LPV techniques and Linear Matrix Inequality (LMI) regions in such a way as to guarantee
the closed-loop behavior in terms of several LMI constraints. To assess the performance of the proposed approach, a two
degree of freedom helicopter is used. |
