The research proposal “Contracts for Control System Design (COCOS)” of Bart Besselink will receive 2 Mio € funding by the European Research Council (ERC). The ERC Consolidator Grant is a prestigious research funding program to support researchers who are in the early stages of their independent research careers and have demonstrated significant potential for conducting high-quality research. Bart proposes a new approach for control system design based on contracts, inspired by ideas from software design in computer science. He will develop a contract theory for control system design that includes techniques for the automatic design of component contracts aimed at optimizing system-level performance, and control design for contract satisfaction. The practical relevance of the theory will be tested by case studies in high-tech manufacturing systems and autonomous vehicles, and supported by efficient computational tools.
