| 摘 要： | 同步发电机励磁控制器是同步发电机控制系统的核心.传统PID控制理论在同步发电机励磁控制上的应用已经非常成熟.但是,这种控制方式存在着定参数、线性控制规律、适应性差的缺点.针对这些问题,采用模糊PID的控制算法,根据输出变化量和变化率在同步发电机运行过程中实现实时调整,起到动态调整PID参数的作用,使系统的动态和静态运行性能得到改善,并使系统具有较强的适应能力,提高控制效果.

| Abstract: | The synchronous generator excitation controller is the core of a synchronous excitation system. The application of traditional PID control theory in synchronous generator excitation has been very ma- ture. But this mode of control only fits for fixed parameters and for a linear control law. To solve these is- sues,a fuzzy PID control algorithm is proposed. According to the output volume changes and the rates of change,the synchronous generator running in real-time and the role of PID parameters should be adjusted. The dynamic and static operational performances of the system conld be improved, its overshoot reduced from 30% to 10% ,thus giving the system a stronger adaptive ability. |
