**ABSTRACT****:**. Summary of the talk: In the first part of this talk, we will give a brief
overview on the linear parameter-varying (LPV) systems theory and describe the
stability and performance analysis for such systems, as well as the standard
tools to examine them. We will then address the sampled-data control design
problem for continuous-time LPV systems. First, to analyze the closed-loop
hybrid system, we map the hybrid system dynamics into the continuous-time
domain using the input-delay approach. The mathematical formulation of
time-delay systems, in general, results in a system of functional differential
equations (FDEs), which are infinite dimensional. We further develop a
delay-dependent approach for control synthesis and propose a set of new
analysis and synthesis conditions that are less conservative compared to the
few existing work in the literature. The developed design formulations that can
handle time-varying sampling rates are based on the solution to a set of linear
matrix inequality- (LMI) based optimization problems. Finally, some of the
applications of the developed formulations will be illustrated.

**Short bio**: Javad Mohammadpour received BS and MS degrees in Electrical
Engineering and PhD in Mechanical Engineering from Sharif Univ. of
Technology, Tehran, Iran and Univ. of Houston, TX, respectively. He was a
Research Assistant Professor of Mechanical Engineering at University of Houston
(from 2008 to 2011) and a Research Investigator in the Naval Architecture &
Marine Engineering (from 2011 to 2012) at the University of Michigan. He joined
The University of Georgia as an Assistant Professor of Electrical Engineering
in August 2012. He has published over 70 articles in international journals and
conference proceedings, served as a PI or co-PI in several funded
projects, served in the editorial boards of ASME and IEEE conferences on
control systems and edited two books on control of large-scale systems and
LPV systems modeling, control** **and applications**.**
