Abstract :
Power system stabilizers (PSSs) are added to excitation system to enhance the damping of low frequency oscillations. In this paper, the design of PSS for multimachine power system (MMPS) using output feedback sliding mode control is proposed. The nonlinear model of a multimachine power system is linearized at various operating points and the linearized model of the plant is obtained. The multirate output feedback sliding mode controller is designed and is applied to nonlinear plant model of the multimachine power system at those operating (equilibrium) points. This method does not require the complete states of the system for feedback and is easily implementable
