摘　　要：研究了控制步长M≥1时动态矩阵控制器(dynamic matrix controller,DMC)的柔化因子和控制增量权重之间的关系,分析了增益对二者取值的影响,并通过仿真实验进行了验证.这一研究为控制增量权重的取值提供了一个量化的指导.The tunable parameters in a predictive controller should be tuned carefully to achieve expected performance. The relationship between two tuning parameters in a stair-like dynamic matrix controller was derived, and the effect of model gain variation was separated. A simulation validated the relationship. The result gives an indirect relation between the weight and desired closed-loop time constant and can quantitatively guide the tuning procedure for stair-like DMC.
