摘　　要：由于动态矩阵控制预测控制算法无法直接控制带有积分环节的过程,针对这一困难,研究了一种适用于积分过程的DMC算法.该算法通过改变经典DMC算法的移位阵,使得有限维阶跃响应系数模型能够对积分过程进行准确的未来输出预测,从而避免了预测截断误差的产生.锅炉汽包水位系统的工业实验结果验证了算法的有效性.由于算法的结构没有改变,计算量也没有增加,该算法较之已有的针对非自衡对象的算法有更强的实用性.Aiming to solve the big difficulty that the dynamic matrix control algorithm (DMC) could not be directly applied on the process with an integral unit,a DMC that can deal with integral process was investigated.The algorithm modifies the shifting matrix of original DMC so that the future output of integral process can be accurately predicted by finite dimension step response coefficients model without the cutting off error.The validity of the algorithm is proved by the industrial experiment to the boiler level system.Compared to other algorithms on the integral process,the present algorithm is more practical because the structure of the algorithm is not changed and computing efforts are not added.
