| 摘 要： | 研究网络环境下控制系统时延的组成与产生机理，提出一种基于动态矩阵控制（DMC）模型预测算法的改进DMC算法。该算法充分利用动态矩阵控制（DMC）算法中冗余的预测输出序列和控制增量序列，在控制数据由于网络时延和丢包而无法及时到达执行器时，实现对网络时延和数据丢包的补偿。并通过实验证明改进算法的有效性。

| Abstract: | The mechanism of production and composing of networked delay were analyzed.Based on dynamic matrix control(DMC),an improved algorithm for network was proposed.In this algorithm,when the actuator node cannot receive the data on time,the predictive output sequence and control increment sequence were used which can avoid the actuator's mis-operating.Finally,the improved DMC algorithm in the actual network is proved based on the experimental platform. |
