Abstract

This research proposes a constant rate reaching law-sliding mode controller (CRRL-SMC) for a synchronous generator (SG) excitation controller to improve transient stability in a small power system. This hybrid excitation controller combines the benefits of a sliding mode controller (SMC) with those of a partial feedback linearizing control to improve transient stability. To meet the proposed controller's design requirements, a reduced-order linearized model is first created from the nonlinear model using the partial linearizing approach, and the control input is obtained using the CRRL-SMC. The Lyapunov theory is then used to verify the system's stability for this designed control input. Finally, simulation studies are used to show the theoretical notion of the developed controller, which is then implemented on SMIB power systems. The findings of the simulation are compared to those of another partial feedback linearizing excitation controller.
