摘　　要：运用现代控制理论，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，推导出了多机系统积分型线性综合最优控制规律（ＩＬＩＯＣ），并与只考虑发电机励磁系统、调速系统控制的线性综合最优控制规律（ＬＩＯＣ）进行了比较。仿真结果表明：在提高系统稳定性极限和改善系统动态特性方面，ＩＬＩＯＣ与ＬＩＯＣ具有相同的能力，但ＩＬＩＯＣ能消除发电机端电压的稳态误差，提高了控制精度。By use of modern control theory, the integral linear integrated optimal control(ILIOC) is derived in this paper. The integral control of generator terminal voltage deviation acts on the excitation system and the speed governor simultaneously. The effect of ILIOC is compared with that of the linear integrated optimal control(LIOC). The result of computer simulation shows that both ILIOC and LIOC have equal capability in enhancing power system stability and improving power system dynamic quality. However, the ILIOC can eliminate the generator voltage steady state error and increase the control precision.
