Referring to the simulation experiment platform of shield machine built by ZheJiang University and ShangHai Tunnel engineering corp., analyzing the work principle of the thrust hydraulic system and the thrust attitude control method of shield machine.

在对盾构技术充分调研的基础上，通过阅读、分析及综合大量文献和现场调研，参照浙江大学和上海隧道工程公司共建的盾构模拟实验台，分析了盾构液压推进系统工作原理及其掘进姿态控制的方法，对盾构液压推进控制系统进行了控制仿真研究。

ABSTRACT The problem of control on nonlinear systems with hysteresis has been put forward since 1960's.

早在上个世纪六十年代就有人提出回滞非线性系统控制问题，但因当时人们对控制的要求比较低，对回滞非线性系统的控制可通过选择适当的器件和用线性。。。

The simulation outcome demonstrates that various control measures after April 20,2003 in Beijing and the public holidays starting from May lst to May 5th have a significant impact on containing the epidemic situation. The most dangerous days, around April 27, when the number of uncontrolled SARS patients in the society reached at its peak, can also be calculated. The SARS infectiousness number newly reported in Beijing has been at a low level since May 20. But simulation experiments describe that it may fluctuate with import of SARS infectiousness from outside Beijing, weakening of quarantine, more social activities, and so on.

同时应用动力学模型，对北京的SARS疫情进行分时间段的模拟与SARS实施控制因素影响分析，结果表明，2003—04—20以后一段时间内实行的各种控制措施，以及5月1日—5月5日的长假对于北京SARS疫情的控制是非常有效的；而4月27日左右北京市社会上未得到有效控制的SARS病人数达到高峰，是最危险的时期。5月20日以后，北京的SARS疫情基本保持在低发的平台期，但是如出现较多的外来SARS病例输入，而内部隔离强度又减弱、社交活动增加等情况下，北京SARS疫情可能会有一定程度的波动与反弹。

The manipulative person can not trust himself, he could not trust other people as well the manipulator tries to control himself by controlling other because he can't control himself. The most common manipulative behaviors include: intimidates, deceive, self- harm, demands, flatters, ingratiation and so on. The worst part of such behavior is that it will split the health professionals in some way. It also causes conflicts between nursing staff and disturbs the emotional status of them. To avoid these situations, all nursing staff should help patients with consistent attitude. In addition, nurses should master behavior of manipulators to reduce the chance of being manipulated. Helping patients to solve their problems may help build up the sense of trust and security and promote self-control. They will beable to increase recognition of behaviors, mature interpersonal relationship and gain self control.

操控者不会信任自己，更不能信任他人，他无法控制自己，所以由控制他人来控制自己，他们最常表现的操控行为，包括：威胁、欺骗、自我伤害、要求特权、谄媚、迎合他人等，比较严重的是他们会分化整个医疗团队的成员，造成成员之间的冲突及情绪上的困扰，为了避免这些状况产生，所有的成员应该要达成共识，用一致性的态度来帮助病人；另外，护理人员要熟知操控者的行为表现，减少被操控的机会，同时灵活运用问题解决方法，来协助病人对他人产生信任感、安全感及增加对自己的控制感，以达到增加行为的认知，学会成熟人际关系，达到自我控制的目的等预期结果。

This paper presents a method to design an intelligent control program for PLC according to its characteristics. It has been used in the jigging control.

本文依据PLC的控制特点，提出了一种PLC智能控制的程序设计方法，并在跳汰机的控制中得到了应用。

And a corresponding nonlinear robust controller is finally constructed. nonlinear systems ; robust control ; feedback inearization ; linear fractional transformation

本文把非线性系统鲁棒控制的μ方法应用到一类可状态反馈线性化的仿射非线性系统鲁棒控制中，提出了非线性鲁棒控制系统的

Linear Fractional Transformation is adopted to translate the control of perturbation to the control of disturbance, then cost index is augmented, and with the min-max method, a robust receding horizon control law is derived. The sufficient conditions for the existence of the control law and closed-loop stability are also presented. The result is extended to time-invariant system with an infinite horizon, and its consistence with the robust control based on the concept of Quadratic Stability is verified.

首先利用线性分式变换，将摄动系统的鲁棒控制问题转化为对扰动系统的鲁棒控制问题；然后通过对性能指标的扩展，利用min-max方法，得到了鲁棒滚动时域控制律，并给出了其存在和使闭环系统渐近稳定的充分条件，并将结果扩展到对定常系统时域无穷的的情况，指出其与现有的基于二次型稳定概念提出的鲁棒控制的一致性。

The simulation results show that this method is effective and successful with strong robustness, and can also be used to some other linear or nonlinear second order systems.

理论分析和仿真表明，这种基于时间最优控制的非线性设计方法具有很好的控制效果和鲁棒性，适用于一类二阶系统的控制。

Thus the magnetic flux and torque are decoupled. In which way, It controls the asynchronous motor in a synchronous way.

本课题应用矢量控制的原理，以电机控制专用的DSP芯片TMS320F240为核心，开发出一套基于矢量控制的变频调速系统。

From the viewpoint of synergic control, a microcomputer control system of pulse MIG welding is developed in this paper, and the hardware structure and control principle of the system are introduced.

本文基于协同控制的思想，研制了一种脉冲MIG焊的微机控制系统，介绍了该系统的组成和控制算法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
