一种新型的动态矩阵控制算法及仿真研究

动态矩阵控制(DMC)中顺序开环控制增量的计算涉及到矩阵的求逆运算，计算量很大，不利于微处理机的在线应用。为减少运算量，使微机编程实现方便，并保持系统优良的控制性能和较强的鲁棒性，在深入理解动态矩阵控制算法的基础上引入了控制增量的期望衰减因子，以期望控制增量在控制时域长度内逐步接近于零。这一思想使得矩阵求逆运算成为数的求逆(倒数)运算，运算量大为减少，运算速度大大提高。基于这一思想提出两种设计方案，并通过计算机仿真研究，证实了算法的有效性。

A New Dynamic Matrix Control Algorithm

The calculation of inverse matrix is involved in Dynamic Matrix Control(DMC) and it restrains on-line application.This paper presents a simplified DMC algorithm.A decay factor is introduced to make the control increment come to zero in the control horizon. Aiming at this idea two schemes are given, which will reduce the computation quantity of inverse matrix. The calculation amount decreases a lot and the velocity is heightened. Computer simulation of these two schemes are given, simulation results demonstrate the effectiveness of the strategy proposed.
