Application of a Dynamic Matrix Control Algorithm Based on Real time Operation System

为了实现实时控制,达到预测的目的,动态矩阵控制(DMC)要求实时计算控制增量,以此作为下一次的控制量。在深入理解动态矩阵控制算法和嵌入式实时操作系统μC/OS-Ⅱ的基础上,提出了新的动态矩阵控制实现方式。通过嵌入式实时操作系统μC/OS-Ⅱ的任务调度功能,实现动态矩阵控制算法,使动态矩阵控制的应用更加简化,减少了计算时间,运算速度得到提高。基于这一实现方式提出了实验方案,并通过实验平台进行研究,证实了算法的有效性。

In order to realize real - time control, and achive predictive function, Dynamic Matrix Control（DMC） requires calculating real - time controlling increment which will be used as next controlling variables. Based on DMC algorithm and embedded real -time system, μC/OS -Ⅱ, this paper presents a new DMC realization scheme. DMC algorithm can be realized by the task management of operating system μC/OS - Ⅱ. This realization makes the application of DMC simple, decreases the calculation time and increases the velocity. Based on this realization scheme, an expriment is given , results demonstrate the effectiveness of the algorithm proposed.
