Electric network is now confronted with market deregulation or overload. Power System Stabilizer (PSS) is used to enhance capacity limits and improve transient stability, and it also make important role in the renewed system. This paper proposes design of excitation control with Fletcher-Powell method, which is non-linear mathematical optimization technique to realize output feedback control. The design procedure and the effectiveness are discussed through 5-machine system models. Scheme of decomposing control matrices for the large network is also discussed for successful application of the method.
