Applying automated control synthesis methods to condition systems requiring state observers

Automated control synthesis methods have been presented in (Holloway et al. , 2000) for a class of fu lly observed plants modeled by condition systems. a class of discrete event systems. For plants which are not fully observed , an automated method to synthesize a state observer was presented in (Gong and Holloway, 2000). In this paper, we show how to apply automated control synthesis methods to plants which feed a state observer. In particular we transform the original plant model into an intermediate form on Which automated control synthesis methods are applied. We prove that the control thus generated is then effective at achieving high level control objectives when then applied to the original plant composed with a state observer.
