摘　　要：随着火电机组单机容量的不断增大,传统PID控制难以满足大型火电机组的控制要求。动态矩阵预测控制是一种先进控制算法,适用于大滞后、大惯性被控对象的控制,应用潜力巨大。在广泛收集动态矩阵预测控制相关研究资料的基础上,分别阐述了动态矩阵预测控制算法和改进后的动态矩阵预测控制算法在火力发电厂热工控制系统中的应用现状,并进行了分析比较。最后对动态矩阵预测控制在未来火力发电厂中的应用,提出了一些看法。Along with the continuously increasing of the unit capacity in fossil power plants, the traditional PID control is difficult to satisfy the control requirements for large scale fossil power units. Dynamic matrix predictive control is an advanced control algorithm, it is suitable for the controlled objects with large time delay and large inertia, so it possesses huge potential for application. On the basis of collecting relative research materials for dynamic matrix predictive control, the current status of applications of dynamic matrix predictive algorithm and the improved dynamic matrix predictive control algorithm in fossil power plants are described respectively and compared. In addition, some comments for the applications of dynamic matrix predictive control in future power plants are proposed.
