摘要
设计了一种基于离线策略表的实时励磁控制器(RSLOEC)。利用发电机实际可能的运行样本依据最优控制原理离线形成反馈增益策略表。通过在线辨识出的样本组[Pe,Ut]经离线策略表插值拟合出最优反馈控制增益,以满足实时性的要求,从而弥补传统LOEC不能适应大干扰的明显缺陷,提高励磁系统的稳定性。给出了Matlab仿真软件包的实现及励磁系统采用RSLOEC提高稳定性的仿真结果。
A real-time excitation controller based on offline strategy sheet(RSLOEC)is designed.using LOC(Linear Optimal Control)method the offline-strategy sheet of feedback plus is generated with most possible practically running stylebooks of dynamo.The optimal feedback plus is acquired via interpolation on the sheet with the online identified stylebook[P e ,U t ].It meets the real-time requirement ,avoids the limitation of traditional LOEC(Linear Optimal Excitation Control)in adapting to great disturbance,and enhances the stability of excitation system.The Matlab simulation software design is provided and the simulative results of an excitation system equipped with RSLOEC(Realtime Strategy Linear Optimal Excitation Control)are given.
