Robust power system stabilizer design based on LMI optimization approach

Robust control theory considers a fundamental and practically important issue in control engineering plant uncertainty. It turns out that many of the simplest questions are very difficult to solve, but researchers have made considerable progress over the last twenty years. In this project, a r...

description Robust control theory considers a fundamental and practically important issue in control engineering plant uncertainty.

In practical, power system stabilizers (PSS) are added to excitation systems to enhance the damping during low frequency oscillations. The main objective of this project is to design robust controller for PSS using Hoo technique based on LMI optimization approach. The nonlinear model of a machine is linearized at different operating points using Power System Dynamic simulation software. A robust controller is obtained using linear matrix inequalities approach.
