同步发电机云模型励磁控制器的设计

云模型是实现定性与定量间不确定性转换的有力工具,它将客观事物的模糊性与随机性结合在一起,解决了非线性与不确定性问题.为此,将云模型引入到同步发电机励磁控制中,根据云模型可实现不同映射关系的原理确定推理规则,设计出一种云模型励磁控制器.仿真结果表明,与传统的PID控制方法比较,云模型控制器具有较强的鲁棒性,对同步发电机运行点变化的适应性较好,增强了系统的暂态稳定性,具有良好的推广和应用价值.

Design of Cloud Model Excitation Controller for Synchronous Generator

The cloud model is a powerful tool to achieve qualitative and quantitative uncertainty transforming.It integrates the fuzziness and randomness of objective things and solves the problem of nonlinear and uncertainties.In this paper,the cloud model is applied to synchronous generator excitation control.According to the principle that cloud model can be realized in accordance with different mapping relations,the inference rules are defined.Then a cloud model excitation controller is designed based on cloud mod...
