Abstract

Accurate solutions of distributed parameter systems may be represented as the sum of an infinite series. Control however, requires low order models primarily for implementation. As such, developing low order models of high fidelity is important in the control of true distributed parameter systems . This work addresses this issue by employing and comparing methods that arrive at low order models either from input-output data or from exact descriptions of the process. Using these approximate low order models, linear and nonlinear feedback controllers are synthesized to address disturbance compensation and model parameter uncertainty. Two candidate processes are introduced and used to demonstrate these concepts.
