Abstract

Synthesizing Linear Time-Invariant (LTI) controllers directly from Frequency Response Function (FRF) measurements is at the core of many successful industrial applications. However, increasing performance expectations necessitate extending these approaches for multiple operating points, viewing the plant as a Linear Parameter-Varying system. The aim of this paper is to develop FRF data based controller synthesis to a larger class of systems by leveraging on recent developments in LPV system theory. The developed method is based on a global LPV controller parametrization with a finite impulse response structure which ensures local stability and performance of the closed-loop behavior by design. A case study confirms that the developed control design procedure, using only measurement data, can be effectively used to design LPV controllers resulting in stability and high performance of the closed-loop system on the specified region of operating conditions in comparison to LTI controllers.
