| Abstract: | A nonlinear robust adaptive excitation controller based on backstepping technique and disturbance attenuation is proposed here. This design is based on a 3rd order dynamic nonlinear model of synchronous machines. The parameter update law and control law presented in the paper can ensure the stability of the closed loop system in the presence of unknown parameters and bounded exogenous disturbances. Simulations were performed for cases of the start up of generator and for 3 phase short circuit and constant external disturbances. The possibility of the extension to multi machines is also discussed. |
