This paper presents a new method to design -xed-structure robust controllers for enhancing stability of power systems. In a robust controller design without structural constraints, a high-order robust controller can be obtained by solving a convex optimization problem. However, it is difficult to implement the high order controller in existing control devices such as SVC and PSS. Since a robust controller design problem with structural constraints can be formulated as a BMI problem, we give a successive approximation algorithm,
