A new approach to the design of distributed parameter systems based on approximation models

The controller design for distributed parameter systems is a challenging task. The simple early lumping approach allows the application of standard control theory tools but the designer has to keep in mind various negative aspects like aliasing, truncation and discretization errors. In this paper a new scheme to minimize these negative aspects in the controller design is presented which adopts a late lumping method by discretization. The scheme leads to the resulting problem formulation of a finite output feedback. The design of a heat conductor demonstrates the application of the new method.
