Title: Compositional Analysis and Control of Dynamical

Systems

Abstract:

 

 

Compositional techniques are widely used in formal verification to check the
correctness of large computer programs. The key problem is the complexity caused

by the interaction of concurrent processes which leads to high dimensions of the

state space. To deal with this problem, the global verification problem for the

overall system is simplified by splitting it into several less complex problems for

the components.

Models of engineering processes can also become very complex since they are

equally characterized by networks of interacting subsystems. Inspired by
solution concepts developed in the area of formal verification, we present concepts

and tools for compositional analysis and control of dynamical systems.

In this talk the focus lies on deduction schemes based on (bi) simulation relations

such as compositional and assume-guarantee reasoning. Our approach provides

insights in various areas of systems theory and control. Explicit connections are

made with classical compositional analysis techniques in systems and control

such as passivity theory and with decentralized control.
