摘要
针对传统PID对直接空冷系统背压控制效果差的问题,提出一种基于动态矩阵控制算法的直接空冷系统汽轮机背压控制方法。根据动态矩阵控制算法建立了背压控制器模型,并将它与PID控制的背压控制效果进行了仿真对比,结果表明:与传统PID控制相比,动态矩阵控制算法的响应更快、更稳定。
Considering poor control effect of the conventional PID control over the back pressure of air-cooled system,a dynamic matrix control( DMC)-based back-pressure control method for the steam turbine of the aircooled system was proposed,including the DMC-based model for the back-pressure control. Having it compared with the control effect of PID control shows that,as compared to the conventional PID control,the DMC algorithm's response speed is faster and more stable.
