摘要
以同步发电机励磁自动控制系统作为研究对象,针对同步发电机励磁控制方式现状,在研究模糊控制的基础上,将模糊PID控制用于同步发电机励磁控制系统。并对所设计的模糊PID励磁控制器进行优化。本文进行了模糊自调整PID控制设计,克服了传统PID控制非线性差、对模型要求高的缺点,并深入进行了基于免疫算法的模糊PID控制设计,把生物学中的细胞免疫原理用于模糊PID控制器中,加强了控制器的自我校正能力,自适应能力,提高了控制精度和速度。
A new approach for synchronous generator excitation control using fuzzy PID system with immune algorithm is presented in this paper. Firstly.this paper designs a fuzzy self-adjustment PID controller to overcome the traditional PID control's shortcomings those are non-liner badly and requesting precise model and so on.And then designs a new fuzzy PID controller which bases on the immune algorithm.The immunity principle is used in the fuzzy PID control which strengthens self-adjustment and adaptive ability of the control system and increases the precision and speed of the controller.
