本文以天然气分布式能源站输入侧燃气锅炉出口蒸汽压力控制为研究对象，针对其大滞后性、大惯性的对象特性，提出了一种基于非参数模型含纯时延的动态矩阵控制(Dynamic Matrix Control，DMC)算法，将该算法运用到能源站输入侧蒸汽压力控制系统中，由MATLAB仿真表明，采用预测控制的蒸汽压力控制系统的稳定性，适应性，鲁棒性以及抗干扰性均优于传统PID控制，蒸汽压力的控制品质得到很大提升，证明可以设计适用于天然气分布式能源站输入侧燃气锅炉出口蒸汽压力控制。

Take the steam pressure control at the outlet of gas-fired boiler of the natural gas distributed energy station as the research object, a dynamic matrix control algorithm based on nonparametric model with time delay is proposed for the object characteristics of large hysteresis and large inertia, applying to the control system. The simulation on MATLAB demonstrates show that the system’s stability, adaptability, robustness and anti-interference performance of predictive control is superior to traditional PID control, and the control quality of steam pressure is greatly improved. It is proved that the design could be applied to the steam pressure control at the outlet of gas-fired boiler of the natural gas distributed energy station.
