Design and implementation of supervisory control schemes in industrial automation systems

Industrial automation systems have a hybrid nature. Such systems contain continuous activities and discrete event activities, interacting with each other. This paper proposes a control algorithm dealing with the continuous activities, as well as the discrete ones. The discrete event controller performs resource allocation and coordination tasks at the higher level of the hybrid system. The direct implementation of the proposed algorithm to the industrial environment is discussed. Also, a hybrid industrial process, batch one, is handled as an application example to test the proposed algorithm.
