     the aim of this paper is to design nonlinear decentralized controllers for multi-machine power systems. the design procedure is based on h control theory and consists of two parts. first, the feedback linearization technique is used. then, a robust controller is designed using the linear matrix inequalities (lmi) approach. the controller has two blocks. one, is a nonlinear function of some local measurable signals such as the generator active and reactive powers, the rotor speed and the armature current. the other block is a pid controller. the linear h theory is used to tune the pid parameters. the method results in a controller which is easy for implementing in practice. the performance of the controller is tested on a sample multi-machine power system model. simulation results show the effectiveness, robustness and good performance of the proposed controller.
