摘要：This paper proposes a Linear Matrix Inequality (LMI) based Η robust controller design employing Wide Area Measurement (WAM) based stabilizing signals as generator speed. A Three-input, Single-output (TISO) controller is designed for a Thyristor Controlled Series compensator (TCSC) in order to mitigate small signal oscillations in a multimachine power system. The controller design has been carried out based on the Η mixed-sensitivity formulation in a LMI framework with pole-placement constraint. The small signal performance of the test system has been examined employing eigenvalue analysis as well as time domain response. The designed controller is found to be robust against disturbances like varying generations as well as load power demand.
