摘　　要：预测控制是20世纪70年代中后期出现的一类新型计算机控制算法。它具有控制效果好、鲁棒性强等优点。采用了广义预测与动态矩阵混合控制算法,该算法中以误差预测补充基于模型的预测,是一种综合预测。文中对单元机组协调控制系统进行了仿真。仿真结果表明,该算法具有较好的控制品质,增强了系统的稳定性和鲁棒性。Predictive control is a new type of computer algorithm appeared in the last 70's. It has perfect control result and excellent robustness. This paper uses the GPC and DMC mixed control algorithm in which model prediction is complemented by error prediction, being a sort of general prediction. In this paper coordinated control system is partly simulated. The results of simulation indicate that the algorithm have good control performance, promoting the system stability and robustness. This method overcame the weakness of some familiar methods, solves the repeat of voting in the internet better, and obtains good result in physically applied.
