With MGT-CCHP system, with which greenhouse gas emissions can be reduced, is su-perior in energy saving and environmental protection, and it is one of the best way to provide clean, relia-ble, high-quality, multi-purpose and small-scale distributed energy. In this paper, MGT-CCHP system as the object of study, predictive control is carried out through multivariable dynamic matrix ( DMC) . Moreover, combined with S function, MGT-CCHP model can be effectively controlled through control parameters selected by Simulink simulation model. In this way, expected values can be tracked quickly to achieve the expected control.%MGT-CCHP系统可以减少温室气体排放,具有节能、环保和高安全性等优势,是提供清洁、可靠、高质量、多用途的小型分布式能源的最佳方式之一.将MGT-CCHP系统作为研究对象,通过多变量动态矩阵(DMC)进行预测控制,结合S函数,用Simulink仿真模型,合理选取控制参数,可有效地控制MGT-CCHP模型,较快地跟踪期望值,达到预期的控制效果.
