Abstract :
In order to improve the marine power system robustness for varying parameters, and attenuate the persistent disturbances effect on power system stability. In this paper, based on the nonlinear robust model of the power system including static load, the storage functions of the system are constructed by integrating nonlinear L2 gain disturbances attenuation theory smoothly into backstepping design methodology. A nonlinear robust controller law are obtained. The controller reflects the nonlinearity of the system and decreases the impact of the disturbances. The simulation results show that the closed-loop system has the ability to attenuate the disturbance using the controller and can resume stable state rapidly when large disturbances happen.
