In this paper, a Global Power System Stabilizer (GPSS) and local PSS have been designed to damp out the inter-area oscillations and local oscillations from the multi-machine power system. On the basis of geometric measure of joint controllability /observability the feedback signal is obtained for the PSS. The parameters of PSS is obtained on Integral of Time Error (ITE) criterion and optimized by Genetic Algorithm. Also, the simulation results confirm that the proposed method effectively damp out the inter-area oscillations from the multi-machine system.
