摘要
首先介绍了最优控制系统综合的李雅普诺夫方法和一种简单实用的非线性系统大范围线性化方法,然后将之成功地应用于同步发电机快速汽门控制器的设计,避免了构造非线性系统李雅普诺夫函数的困难,为电力系统暂态稳定控制的研究作出了新的探索。获得的控制器完全基于当地量的反馈。
A Lyapunov method for optimal control system design and a simple and practicable approach for implementing global linearization of nonlinear systems are presented. They are successfully applied to design the fast valving controller of synchronous generators. The difficulty for constructing the Lyapunov function of the nonlinear system is avoided, which provide a new way for study of transient stability control in power systems. The proposed controller is purely based on local feedback, and can be easy implemented on line.
