Abstract
Current production systems are becoming more complex: manufactured products are increasingly technical, production components are more specific, and control specifications are rapidly changing. Thus, formal methods and tools are becoming essential to support the automated development of control systems. We propose to develop a tool for the synthesis and implementation of modular/distributed supervisory control for Automated Manufacturing Systems (AMS). To reduce the computational complexity, we divide the control problem into local and global controls. Local Controllers (LCs) are designed for the individual subsystems, then global dependencies are added to the LCs to cooperatively execute the control actions. The tool provides a distributed control, interpreted as Grafcet (standard IEC 60848), that can be lately converted into any suitable IEC 61131-3 standard programming language for PLC programming purposes. It is based on Model-to-Model (M2M) transformations implemented in an Eclipse Modeling Framework (EMF) environment.
