Semi-global Robust Controller Design for Polynomial Fuzzy Systems with Uncertainties and Input Constraints

Abstract

This paper presents a non-convex sum-of-squares approach to semi-global robust control of polynomial fuzzy systems with uncertainties and input constraints. We treat altitude control of a paraglider-type UAV which contains uncertainties as a complicated and real design example. The control results demonstrate the effectiveness of semi-global robust stabilization in comparison with global robust stabilization.
