Abstract:The adaptive and robust generator excitation controller with terminal sliding mode for multi-machine power system is designed.L2-gain disturbance attenuation,adaptive backstepping method and terminal sliding mode control are combined to adaptively estimate the uncertain damping coefficient of generator and possess robustness to disturbance.Its design steps are given.Simulative results for 2-area 4-machine power system show that the designed controller restrains the power oscillation quickly,improves the sys...
Keywords:terminal sliding mode control  adaptive  robustness  electric power system  stability
