Computer Aided Control System Design

Computer aided control system design refers to numerical methods for the design of controllers and on modeling, discretization, and simulation of systems with controls and observations. The work on effective control setups combines methods from the fields of model order reduction, matrix equations, and scientific computing.

One of our core areas is the computer aided control of system governed by (partial) differential equations. Among others, we develop numerical algorithms for robust control and stabilization of descriptor systems that are obtained from the discretization of differential equations with additional constraints like the Navier-Stokes equations.

Within the vast research field of numerical methods for control systems, we 
focus on the construction of H-infinity controllers or the computation of system norms by using spectral information of certain structured matrix pencils. Apart from the developments in the theory, our algorithms are casted into efficient and robust software environments.
