Automated fault tolerant control synthesis based on discrete games

This paper focuses on how fault tolerant controllers can be designed based on discrete game abstractions of piecewise-affine hybrid systems (PAHS). The proposed method aims at automatic generation of the controllers by converting the discrete games to timed games, which can be solved by the UppAal toolbox. Winning strategies to the games are then refined to piecewise-affine control strategies which is a type of gain scheduling. The feasibility of the method is shown through the automated design of a fault tolerant controller for a simple example.
