  • A two-step method for designing controller for a single area power plant (SAPP) is proposed. In the first step, a lower-order (lth-order) model for a higher-order (hth-order) power plant is obtained using dominant pole retention and Padé approximation method and a controller is designed for this model. This controller is then implemented to original higher-order power system in the next step. The method preserves stability and disturbance rejection is also satisfactory.
