摘要:励磁装置是指同步发电机的励磁系统中除励磁电源以外的对励磁电流能起控制和调节作用的电气调控装置。自50年代以来，随着时代的进展，不论是在控制理论还是在电子器件的研制和实际应用方面，取得长足的进展，这些成果进一步促进了励磁控制技术的发展。

　　　励磁系统是水电站设备中不可缺少的部分。在目前在电力电子装置的研究中，为了克服常规PID励磁控制已经不能满足系统运行的动态和静态性能，设计一种新的模糊PID控制，结合常规PID控制的优点。

ABSTRACT:Excitation device is a synchronous generator excitation system, in addition to the excitation power other than the excitation current from the control and regulation of the electrical control device. Since the 1950s, with the progress of the times, both in the control theory and made ​​considerable progress in the development and practical application of electronic devices, these results further promote the development of the excitation control technology.

     The excitation system is an indispensable part of hydropower equipment. Power electronic devices, in order to overcome the conventional PID excitation control can not meet the dynamic and static performance of the system operation, design a new fuzzy PID control, combined with the advantages of the conventional PID control.

Key words: excitation system; automatic control; fuzzy controller; MATLAB simulation
