摘　　要：为了分析发电机在考虑励磁与汽门控制作用下的镇定性问题,依据广义Hamilton系统的镇定理论,利用能量-Casimir函数构造了一个扩张的Hamilton函数,推证了该扩张的Hamilton函数的Hesse矩阵的正定性,从而证明了该扩张的Hamilton函数是系统的Lyapunov函数。并证明了所讨论的控制系统可以被常值反馈镇定,仿真结果验证了上述论证的正确性。For analyzing the stabilizability of excitation and steam-valve control system of a generator, this paper constructs an extend Hamilton function by using energy-Casimir function based on stabilizability theory of generalized Hamilton system. And it is deduced that the extend Hesse matrix is a positive definite matrix, then the conclusion is obtained that the extend Hamilton function is the Lyapunov function of the system. And it is proved that the system can be stabilized by constant feedback control. The correctness of the proposed analysis is verified by the simulation results.
