Design of Optimal Excitation Control System for Synchronous Motor

介绍了线性最优控制系统的设计原理,并基于最优控制原理建立了线性最优励磁控制器的数学模型。通过MATLAB仿真模型的建立,在三相短路的运行实验情况下,将同步电机励磁控制系统与传统的励磁手段相比较可知,前者具有更好的静态和动态稳定性。

Introduction was made to the design principle of linear optimal control system. Based on the optimal control principle, this paper constructed a math model of linear optimal excitation controller. Via MATLAB Simulation model’s establishment, under operational experiment conditions of three-phase short circuit, the synchronous motor excitation control system was compared with the traditional excitation means. The result shows that the synchronous motor excitation control system is with better static and dynamic stability.
