Steam Valve Opening Control of Multi-Machine Power System Based on T-S Fuzzy Model

针对多机电力系统气门开度的控制问题,构建了具有非线性关联作用的多机电力系统数学模型,并在T-S模糊模型局部线性化建模方法的基础上进行改进,提出了一种带有关联项的非线性系统的线性化模型。针对得到的T-S模糊模型,进行了基于观测状态的分散控制研究。最后通过Matlab进行仿真验证,结果证明所设计的多机电力系统线性化模型是可行、有效的。

Focused on the steam valve opening control,this paper presented a linear model for nonlinear systems with interconnections based on the improved local linear T-S fuzzy model of the multi-machine power systems with nonlinear correlation function. Decentralized control of the model under the observation condition was proposed. M atlab simulation verified the feasibility and validity of this model.
