  2. Abstract:
  3. Design of a classical controller is based on output feedback and structure of the controller. From modern control point of view, the information of input signals, output signals and internal behavior of the system are presented in state space model. In this paper, modern control is used to increase small-disturbance stability of power systems. Although many of existing power plants prefer to use classical Power System Stabilizers (PSS), these controllers have their own problems. Digital implementation of modern controllers is considered as a good advantage of modern PSS. In this paper, a modern control based PSS is designed for Bistun power plant and its output results are compared to the existing classical PSS. This modern PSS design starts with a LQR structure and after comparing advantages and disadvantages of the design, it results in a LQG PSS. There is also a discussion on input signal of the controller
