Abstract

Batch control is characterized by procedural control that is realized according to operating procedures to accomplish tasks. However, operating procedure synthesis takes considerable time and effort as the complexity of a batch process increases. To solve the operating procedure synthesis problem, a modeling technique is needed to represent the concurrent dynamics of a batch process. This paper aims at developing a method to synthesize operating procedures and procedural controllers for batch processes. For this purpose, it first views a batch control system as a discrete event system and next uses hierarchical Petri nets to represent information about process, plant, and schedule. It then presents a method to synthesize operating procedures. It also discusses the verification of synthesized operating procedures and last presents a method to synthesize procedural controllers.
