摘　　要：本文从电力系统运行实际出发，考虑发电机励磁系统、调速系统控制的同时，对发电机端电压偏移量施加积分控制，推导出了系统线性化增广状态方程式，并在此基础上推导出了线性综合最优控制规律（ＩＬＩＯＣ）。仿真结果表明：在消除发电机端电压的稳态误差和提高控制精度方面ＩＬＩＯＣ优于ＬＩＯＣ。By considering the power system operation condition and excitation system and speed governing system,we achieved the power system linear extended state equations as using integral control to generator extremity voltage deviation,and the integral linear integrated optimal control (ILIOC) was obtained in this paper.The result of computer simulation shows that ILIOC is superior to LIOC in eliminating generator extremity voltage steady-state errors and increasing the control precision.
