Abstract：In order to realize the robust control for a class of non-lower-triangular interconnected multi-input system, we propose the decentralized nonlinear adaptive L2 attenuation control method based on the state measurement. The universal calculation formulas are summarized. Because the K-Class functions are applied in the control law, the convergence rate of the state parameters is improved. This new L2 attenuation control method is applied to the excitation control for the multi-machine power system;the simulation results show that when serious disturbances appear in the power system, comparing with the traditional L2 attenuation control, this new method can attenuate disturbances effectively, accelerate the response of the state variables, and improve the transient stability of the power system.
