摘要
针对不确定有界长时延网络控制系统,研究动态矩阵控制(DMC)算法及其稳定性问题。首先基于多输入多输出状态空间模型,推导针对长时延网络化控制系统的DMC算法;然后,利用Lyapunov稳定性理论和线性矩阵不等式方法,给出闭环控制系统渐近稳定的充分条件;最后,通过对倒立摆的实时控制验证笔者算法的有效性。
The dynamic matrix control（DMC） algorithm and its stability were investigated for networked control system with uncertain but bounded long time-delays.Firstly,having multi-input and output state-space model based to derive DMC algorithm for networked control system with long time-delays,and then having Lyapunov stability theories and linear matrix inequality method used to present sufficient conditions that can guarantee the asymptotical stability of the closed-loop system,finally,the real-time control example of an inverted pendulum was used to demonstrate effectiveness of the proposed algorithm.
