摘　　要：将大型汽轮发电机系统作为一类复杂开放系统 ,基于非线性科学分析了该系统的动力学特性 ,论述了该系统轴系扭振的原因及其本质。在此基础上 ,提出了大型汽轮发电机组轴系扭振的递阶智能控制方案 ,并根据非线性科学理论分析了该智能控制系统的稳定性。所提出的方法为有效地抑制轴系扭振提供了新途径。The causes and essence of the torsional oscillation of large turbogenerator which consider as a kind of complex open system was investigated by using nonlinear science theory. The hierarchical intelligent control scheme of the large turbogenerator is suggested and the stability of the intelligent control system presented is analyzed by applying nonlinear science theory. A new way to damp system oscillation is given in this paper and shows that the method is effective.
