Real-time variable-plus excitation controller based on offline strategy sheet

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 stylebookP 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.
