摘　　要：提出了一种基于模糊MAMDANI推理算法的模糊监督控制器,采用各个区域的频率偏差作为控制器的输入。监督控制器作为一种前馈补偿,设计输出为一个ACE的倍数,加快调节过程,到达稳态。经过实验仿真数据对比,说明提出的监督控制器能有效提高系统的稳定性。In this paper, a new supervisory controller which is designed based on the Mamdani inference method of fuzzy control is proposed. The area frequency deviations are adopted as input variables, and the output is chosen to accelerate the response speed of controller in order to compensate the disorder interactions. The controller in this way can quicken the adjustment, and come to a stable state uhimately. Compareing the simulation results with those of conventional control methods, we draw a condusion that the supervisory fuzzy controller can be found better performance in keeping the stablility of the system.
