This is a project at Chalmers consisting of implementing a control system generated from Supervisory Control Theory.
"Operation sequencing and resource safety is a non-trivial task within modern manufacturing systems. Typically, this task is handled manually which is time-consuming and error-prone. Whether a particular system works correctly is determined by how long it has been able to function without severe error. Obviously this situation is not sustainable and can be greatly improved by using software tools and mathematics to guarantee correct functionality. Such "model-based formal methods" is one main part of the research within the Automation group at Chalmers. This project aims at implementing a proof-of- concept of existing methods."
Present at IFAC 2014
Our paper was good enough to be presented by our examiner, Martin Fabian, at IFAC 2014. http://www.ifac2014.org/
1. Create a model of the sequence:
2. Express it as automatas:
3. Extract guards to forbid bad behaviors e.g. deadlocks and forbidden states:
4. The HMI is implemented in HTML5 and AngularJS that communicates to the OPC server of the PLC:
