Abstract

This paper introduces a new technique to design applicable one-point feedback controllers for distributed parameter systems (DPS) with uncertainty. The technique is an extension of the Quantitative Feedback Theory (QFT) to DPS, considering spatial distribution as another parameter of uncertainty. Working on the classical frequency domain, the technique avoids complex double Laplace transforms, partial differential equations, etc., but still represents spatial distributed configurations. The paper extends the classical QFT performance specifications used in lumped systems by introducing a set of inequalities for DPS. An example compares former approaches to the proposed one.
