摘　　要：建立了三阶发电机数学模型,选取系统输出函数的线性组合作为系统的滑模面,利用新的状态变量构造正定的李雅普诺夫函数,得到了控制变量的表达式。设计了二阶的ESO跟踪系统存在的外部扰动并补偿它,改善了系统的暂态稳定性。MATLAB/Simulink的仿真结果证明了该方法的有效性。This paper establishes the third order mathematical model of generator, selects the linear combination of system output function as sliding mode surface, works out the expression of control variables by positive define Lyapunoy function formulated by the new state variables, designs the external perturbation in the second order ESO system and its compensation, and improves the system transient stability. The result of simulation by MATLAB/Simulink proves the effectiveness of the method.
