Summary:This study presents design of a nonlinear controller based on combination of backstepping technique and sliding mode control technique for a single machine infinite bus (SMIB) network in order to improve transient stability. The main goal of controller design is to control the excitation voltage of the synchronous generator. Comparison of response of the proposed controller and existing backstepping controller in presence of disturbance shows that it exhibits rapid response, smooth convergence and disturbance suppression. A standard third order model of synchronous generator is used to design the proposed controller.
