About the trajectory synthesis to go back to nominal mode for a class of   hybrid systems
  This paper presents basis parts of a new method to synthesize a return trajectory for a reactive process from a default mode to one of the nominal modes. The process is modeled with a hybrid automata. The purpose consists of doing a backward reachability analysis from the final state to the initial state, in the state-space. This method is applied to a batch system.
