LMI‐based robust H2 control design with regional pole constraints for damping power system oscillations

This paper presents an LMI-based robust H2 control design with regional pole constraints for damping power system oscillations. The proposed controller uses full state feedback. The feedback gain matrix is obtained as the solution of a linear matrix inequality (LMI). The technique is illustrated with applications to the design of stabilizer for a typical single-machine infinite-bus (SMIB) and a multimachine power system. The LMI-based control ensures adequate damping for widely varying system operating conditions and is compared with the conventional power system stabilizer (CPSS).
