| 摘 要： | 同步发电机励磁汽门综合控制由多变量非线性DAE子系统模型来描述.本文扩展了非线性常微分方程系统的反步控制方法，研究了其镇定控制问题.首先若被控系统的向量相对阶存在，那么可通过一个微分同胚和反馈控制实现系统的解耦和等价转化.然后基于等价系统，利用反步方法设计其镇定控制器，使得整个闭环系统渐近稳定.最后基于MATLAB进行了仿真，仿真结果验证了本文所提方法的有效性.

| Abstract: | The excitation and valve control of synchronous generator is described by a multi-variable nonlinear differential-algebraic subsystem model.A stabilization controller is designed based-on backstepping control method for such systems.Firstly,if the vector relative degree exists,then the controlled systems can be decoupled and transformed equivalently by a diffeomorphism and a feedback control.Then the backstepping method is adopted for the equivalent system to design the stabilization controller,through which the whole closed-loop systems is made asymptotically stable.Finally the simulation is conducted based on MATLAB,and the results show the validity of the method proposed in this paper. |
