摘要
We propose a fault tolerant control (FTC) scheme that compensates for sensor faults in linear parameter varying systems via multiple sensor switching. The scheme consists of a closed-loop system with an estimator-based feedback tracking controller that switches between sensor-estimate pairings based on a sufficient set separation criterion, which considers both model uncertainty and system disturbances. Under the proposed scheme, preservation of closed-loop system boundedness is guaranteed for a wide range of sensor fault situations. An example is presented to illustrate the performance of the FTC strategy.
