摘要
针对一类关联可测非线性广义子系统,研究了其全局镇定控制问题。首先通过微分同胚变换实现了子系统模型的等价变换。然后基于反推控制方法,在充分考虑大系统其余部分关联输入对子系统影响的情况下,给出了非线性控制器的设计方案,使得闭环子系统是渐近稳定的。最后将该方法应用于电力系统中的一台同步发电机的分散非线性汽门控制器设计,仿真结果验证了所提方案的有效性。
This papes discusses the global stabilization problem for a class of nonlinear singular sub-systems whose interconnection inputs are local measurable. Firstly, an equivalent transformation is obtained through differential homeomorphism. Then the control scheme is designed based on backs＇tepping approach such that the closed-loop sub-systems are asymptotically stable. Finally, a nonlinear governor controller is designed for a synchronous generator in the multimachine power systems. The simulation results are also given.
