根据对象的特点和节能要求,对供热系统提出预测控制方案。首先介绍了基本动态矩阵控制(DMC)算法,给出了预测模型、滚动优化控制和误差校正的构成。为了提高实时性,接着给出了DMC简化算法。然后,基于时间序列分析原理提出用预报误差校正代替误差校正的算法。最后通过仿真实验,给出各种算法的仿真结果并对结果进行了分析。

This paper presents predictive control scheme of heat supply system based on the demand of energy saving of building heat supply and of the feature of heat supply object. First, it introduces basic dynamic matrix control algorithm (DMC), and gives the constitute of predictive model, rolling optimization and error correction. Next, in order to enhance real-time property, DMC simplification algorithm is analyzed and given. Then, it is presented to use predication error correction to replace general error correction in dynamic matrix control based on time series analysis method. Finally, the effectiveness of algorithms is illustrated by simulation results.
