碩士 === 國立交通大學 === 控制工程系 === 85 === In this thesis, we propose a practical solution for the control problem ofdiscrete event systems. First, the control theory of discrete event systems is reviewed and a general- purpose two-tiered control structure is introduced. Based on that structure, a modified method to design the controller and supervisor is presented. A state-based specification interpretation method andassociated solution algorithm are proposed. These are different from the transition-based methods. As a result, the complexity of the problem is highlyreduced and the supervisor can be synthesized efficiently and systematically. The proposed method are applied to the supervisory controller design of an RTP( Rapid Thermal Processor ) machine in semiconductor manufacturing. A CAD environment based on object-oriented programming is also developed to speed- upthe design process.
