摘要
为进一步提高水轮机的调节性能和控制精度,针对水轮机调节系统提出了一种基于线性矩阵不等式(LMI)的扰动观测状态反馈控制策略.首先,对水轮机调节系统进行了建模,并设计了一种基于 LMI的扰动观测状态反馈控制策略,该策略综合考虑了水轮机的运行状态及扰动观测值;然后通过 LMI完成了该控制器的设计与分析;最后,为了验证所提控制策略的有效性和鲁棒性,通过仿真试验进行了测试.结果表明,与传统的控制方法相比,该扰动观测状态反馈控制策略可有效提高水轮机调节系统的响应速度、准确性和稳定性,且降低了系统对扰动的敏感性.
Abstract
In order to further improve the regulating performance and control accuracy of hydraulic turbine,this paper presents a disturbance observer based state feedback control strategy for the hydro-turbine governor system,which is based on Linear Matrix Inequalities(LMIs).Firstly,a modelling of the hydro-turbine governor system is conducted,and a disturbance observer-based state feedback control strategy based on LMIs is designed.This strategy comprehensively considers the operating state of the hydro-turbine and disturbance observation values.Subsequently,the design and analy-sis of this controller are accomplished using LMIs.To validate the effectiveness and robustness of the proposed control strategy,simulation experiments are conducted.In comparison to traditional control methods,the results demonstrate that the disturbance observer-based state feedback control strategy can effectively enhance the hydro-turbine governor sys-tem's response speed,accuracy,and stability while reducing its sensitivity to disturbances.
