基于模糊自调整PID控制的同步发电机励磁研究

随着发电机单机容量和电网规模的增大，发电机组及电力系统对励磁控制在可靠性和动态品质等方面提出了越来越高的要求。在日益复杂的被控过程面前，由于不可能得到过程的精确数学模型，传统的基于精确模型的常规PID控制模型已不能满足系统的动态和静态运行性能要求;为了克服这个缺点,设计了一种新型的基于模糊自调整PID的控制系统。运用Simulink对传统PID与模糊自调整PID在励磁控制过程中进行仿真比较，并比较了在加入干扰信号情况下两者的性能，结果表明模糊自调整PID具有明显动态运行性能和抗干扰能力优势。

Simulation of synchronous excitation controller based on fuzzy self-regulation PID control

With generator unit capacity and the scale of transmission-line system of electric power becoming larger and larger,higher and higher standard demands are made on reliability and dynamic quality of excitation control for generating set and electric power system.Being confronted with more and more difficult in control process,and without exact mathematic model,the traditional and general PID control,which is based upon exact mathematic model,is no longer satisfying the demands of the dynamic and static quali...
