The In this paper the problem of reconfiguration in hierarchical control of piecewise-affine systems in discrete time is considered as the choice of input constraints applied to the low-level control. It is shown how such reconfiguration can provide fault-tolerance to actuator faults while reducing the computational complexity of low-level control. The approach is based on partitioning the state space while taking into account multiple possibilities for the inputs available to low-level control. A so-called "reconfiguration database" is computed at design-time which determines the input constraints that provide for reachability between regions of a state-space partition. This database is used as a basis for reconfiguration decisions at runtime.
