为了实现一类非下三角结构互联多输入系统的鲁棒控制，提出一种基于状态量测的非线性自适应L2增益分散干扰抑制方法，并给出了规律性计算公式，克服了反复递推设计的不足，通过控制律中引入K类函数，提高了状态变量的收敛速度。该方法应用到了多机广域电力系统分散励磁控制中，仿真结果表明：在大扰动情况下，相对于传统L2增益抑制方法，新方法能够有效抑制外部干扰，提高各状态变量的响应速度，对于增强电力系统的暂态稳定性具有重要意义。

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.
