Advanced control design processes are model-based and the control law design problems are also often multi-disciplinary in their nature where many different, often conflicting design requirements have to be fulfilled simultaneously. Tackling control design problems for critical processes in aerospace and robotics demands for efficient and reliable computer-aided methods and tools. We support the computer aided approach by the following basic techniques: multi-disciplinary modelling and simulation, optimisation-based control law design and assessment, non-linear controller synthesis and linear system techniques.
