We here consider the state avoidance control problem. We provide algorithms that, based on a particular decomposition of the set of forbidden states, locally solve the control problem (i.e. on each component without computing the whole system) and produce a global supervisor, that can be efficiently evaluated on the fly %U http://www.irisa.fr/vertecs/Publis/Ps/2005-ifac.pdf %8 July %D 2005
