滞后

The reasons are various and the outmoded theory research is one of the primary factors.

其中，理论研究滞后是其主要原因之一。

However, because of the drawbacks of management there are many problems existed in mineral resource of our country, such as universal overdevelopment of mineral resource, the low use efficiency of resources disposition, the unreasonable mining industry economic structure and environment degeneration and so on.

然而，由于管理的滞后，我国矿产资源普遍存在过度开发、资源配置效率和利用效率低下、矿业经济结构不合理、环境退化等问题，特别是我国正处于工业化快速发展时期，资源需求急速增长，资源短缺已成为制约国家和企业发展的"瓶颈"。

Overexpansion of the government scale will cause problems such as low administrative efficiency, heavy fiscal burden, rent-seeking of public power and the underdevelopment of the third sector.

In accordance with these questions, one kind of method solving these issues was put forward in this text, and namely adopting mathematics to build the method of pattern, by w-ay of studying the big needle drum system of PASSIM's cigarette machine, to use the mathematical model of big needle drum system of " black box " method establishment, and uses whole parameter and the correlation coefficient to map out the big needle drum system mathematical model of least square method, the question time lapse that what in accordance with the system exists pure adopts Smith compensator to estimate the compensator in advance solving the issue of system lag, and uses whole fixed method of frequency conversion control engineering and PLC's control engineering and PID etc to put into effect transforming to the system, and finally by way of theory verify and reality to verify to prove the success of system transformation.

针对这些问题，本文提出了一种解决这些问题的办法，即采用数学建模的方法，通过研究PASSIM卷烟机大针鼓系统，利用"黑匣子"方法建立大针鼓系统的数学模型，并运用最小二乘法整定出大针鼓系统数学模型的参数及相关系数，针对系统存在的纯时滞问题，采用史密斯预估计补偿器来解决系统滞后的问题，并利用变频控制技术和PLC控制技术、PID参数整定方法等对系统实施改造，最后通过理论验证和实际验证证明了系统改造的成功。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
