Applied in cigarette control system of automation logistics system, industrial equipment field bus control technology has become the most effective tool to solve the question that traditional cigarette production exist raw material prepare time to be long and weak adaptability to market. And its open structure system has created the condition to extend for the system expansion. That applying PROFIBUS bus technology in the control system of cigarette automation logistics system, and solving the existed latent problem, is one of research results for the paper.

将工业设备现场总线控制技术应用于卷烟自动化物流系统的控制系统之中，成为解决传统卷烟生产存在的原材料准备时间较长，适应市场能力弱的最有效的工具，而其开放性的结构体系，又为系统的扩展和延伸创造了条件，将PROFIBUS总线技术应用于卷烟自动化物流系统的控制系统之中，并解决存在的潜在问题，是本文的研究成果之一。

The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.

研究结果表明：系统在较小的延时下仍能保持一定的稳定，随着延时的增大，系统的控制精度有所降低；而较大的随机延时不但降低系统的总体快速性，同时，使系统的稳定性和控制精度明显降低，而当随机延时大到一定程度时，系统的稳定性难以保证。

The user only need prepare a browser to enter into the system, without any special client-end programs. The developing environment is independent from implementation environment, which could bring expendability, security and re-usability to the system. Any change of database structure will not affect the client too, which can make the maintenance easier.

Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。
