摘　　要：介绍了基于坐标变换和反馈控制理论的 2种反馈线性化方法 ,即微分几何法、逆系统法 ,提出无论在单变量还是在多变量仿射非线性系统中 ,微分几何法与逆系统法是一致的 ,逆系统法更直接 ,更适合于工程应用。运用逆系统法推导了TCSC稳定控制器的控制原理 ,并与用微分几何法和用直接大范围线性化法设计的控制器进行比较 ,表明它们具有相同的控制效果 ,即均能提高电力系统的暂态稳定性。Two feedback linearization methods differential geometric method and inverse system method are presented. In the affine nonlinear system with either mono variable or multi variable, the inverse system method is equivalent to the differential geometric method, but the latter is more direct and convenient for engineering application. TCSC stability control law is developed by using the inverse system method. Compared with the control laws developed by using the differential geometric method and the direct wide range linearization method, it shows that they have the same control effect on enhancing the transient stability of power system.
