A Case Study in Model Reduction of Linear Time-Varying Systems
Research output: Chapter in Book/Report/Conference proceeding › Paper in conference proceeding
In this paper the balanced truncation procedureis applied to a time-varying linear system, both in continuous and in discrete time. It is discussed how to obtain the reduced-order systems by using certainprojections instead of direct balancing. An approximative zero-order-hold discretization of continuous-time systems is described, and a new a priori approximation error bound for balanced truncation in the discrete-time case is obtained. The case study shows that there are several advantages to work in discrete time, including simpler implementation and less computations.
