Abstract :
Large-scale control systems appear frequently as mathematical
models for many practical fields such as heat conduction,
electrical circuits. Simulation of such systems requires
solving equations whose order can reach dozen of thousands.
Besides, in many cases, these systems depend on parameter which
makes the simulation more challenging. In this talk, first we will
give an introduction to model order reduction of
parameter-dependent linear time-invariant systems as well as a
review of interpolation-based methods. Then we will explain why in
some cases, we have to do it in the framework of interpolation on
matrix manifolds. Finally, we will present some numerical examples
for illustrative purpose.
