Modeling - a Control Engineering Perspective
Prof. Karl Johan Aström (Lund University; Sweden)
Modeling is a central part of control engineering. Models are used for many tasks: simulation, control design, implementation and verification. The models have different complexity, high fidelity models are used for validation, but control design is typically based on simplified models, such models are also part of the control laws. An important aspect is the role of models in the design process where they are used in all phases. This talk gives an overview of modeling from the control engineering perspective. It also contains a little nostalgia, presenting work that I did jointly with researchers, who are now well known in the Modelica community. There will be a short discussion on modeling from data or from physics. A challenge to extend formal verification for discrete systems to cyber-physical systems will be presented. The conclusion is that models will continue to have a central role in computer-based design-build engineering that will become the norm for most product designs in the future.
