时控的

In the last chapter,we study the control problems of the distributedparameter system governed by a class of higher order pseudohyperbolicequation related to the symmetric regularized long wave equation.we havediscussed the controllability and optimal control problems.we have obtainedcompatibility condition of the constraint when the state is controllable,therepresentation of the optimal control for both the time optimal control problemand the optimal control problem of minimum energy type,and the equationsatisfied by the minimum time.we have shown that the optimal control belongsto the boundary of the admissible control set.

在第六章中，我们研究了与对称正则长波方程相关的一类高阶拟双曲型方程支配的分布参数系统的控制问题。讨论了系统的状态能控性问题和最优控制问题，给出了状态能控时的约束相容性条件，给出了最速控制问题、最小能量型最优控制问题的最优控制表达式和最速时间所满足的方程式，证明了最优控制属于控制集合的边界。

The compensator was H = 2370s . The results of simulation showed that attenuation factor of the first order of the third control system was as much as ten times of the value of the system without controller.

通过仿真表明，采用速率传感器，在前三块帆板上布置压电驱动器时，一阶最大衰减因子为无控时的10倍，可以使脉冲衰减时间缩短15倍。

"Each float contains a single pole mercury switch which actuates when the longitudinal axis of the float is horizontal, and deactuates when the liquid level falls 1"" below the activation level."

每个浮控开关包含一个单极水银开关，当浮球的纵轴处于水平位置时，开关打开，当水位低于启动位置1英寸时，开关关闭。

每个浮控开关包含一个单极水银开关，当浮球的纵轴处于水平位置时，开关打开，当水位低于启动位置1英寸时，开关关闭。

"Each float contains a single pole mercury switch which actuate s when the longitudinal axis of the float is horizontal, and de actuate s when the liquid level falls 1"" below the activation level."

每个浮控开关包含一个单极水银开关，当浮球的纵轴处于水平位置时，开关打开，当水位低于启动位置1英寸时，开关关闭。

The dynam ometer test results showed that the injection timing had a large effect on the f uel consumption and it must be accurately and precisely controlled,when the engi ne was working at low load.

试验表明：喷油时刻对于降低燃油消耗率影响很大，小负荷时必须对喷油时刻进行精确控制；采用电控低压半直接喷射系统后，发动机在全负荷时的燃油消耗率下降显著，同时功率与扭矩也稍有增加。

Prove by this research, the revaluation of Taiwan Dollar is advantageous to raise up the REITs prices. And the revaluation could be come from the prospect ion of global investment to the local real estate market. Besides, Granger Casuality has demonstrated the prices of construction group that has got ahead of REITs prices,and whenever it goes up, REITs will be lifted up at the same time.Moreover, REITs issued by Financial Holding is performed better than other issuers.Maybe the reason is the Financial Holding operated the higher quality targets as the trust objects than others.

经由本研究多元回归模型实证发现，台币的升值，有裨益於REITs价格的提升，而台币的升值有可能源自於外资对台湾房地产商办的看好；此外由Granger因果关系检定可得知，营建股股价领先REITs股价的走势，亦为当营建类股走强时，REITs类股也会为之水涨船高，此外金控发行REITs表现亦优於非其他REITs的表现，此有可能金控机构拿出来信托的标的物较为优质所致。

Based on characteristic of silicon microwaves, a new method of pneumatic pressure control is presented.

本文针对硅微控阀门的特性，提出了一种新的气体压力控制方法，设计了基于微机电硅微控阀门的气体压力控制系统，对系统的传感器调理电路、控制电路进行了设计，解决了小压力和低流量时的压力精密控制问题。

Microcontroller through the infrared sensor part and the voice-activated sensor part of the coming changes in the signal to determine whether there are outsiders, if sent through the speakers or the diode to the police; infrared sensors, infrared emission through the launch tube to the receiving tube, two between elements of a connecting via infrared, when there are objects stand in the middle, they then pass on the changes in level microcontroller; Similarly, voice-activated sensor is converted into electrical signals into acoustic signals and then transmitted to the microcontroller; keyboard is used to set the alarm trigger conditions.

单片机通过红外传感部分和声控传感部分的传来的信号的变化来判断是否有外来者，如有则通过扬声器或者发给二极管来报警；红外传感器是通过发射管发射红外线到接收管，两个元件之间通过红外线进行连接，当有物体挡在中间时，便把电平的变化传给单片机；同理，声控传感器是把声音信号转换为电信号然后传送给单片机；键盘是用来设置报警触发的条件。

The system uses PID controller and fuzzy controller to design automatic control loops, a study of fuzzy three-element feed-water control system for a CFB municipal waste incinerator is introduced. The incinerator is faced with problems such as large-scale fluctuation of furnace heat load and low regulation resolution of main control feed-water valve. The fuzzy logic control system is applied to modulate PI control parameters according to steam drum water level to fit fluctuated heat load, the inner and outer control loops are realized in an asynchronous way to effectively decrease regulation time and improve regulation precision.

针对垃圾炉炉膛负荷波动较大，同时给水调节阀门执行机构的调节精度较低的现状，在传统三冲量串级汽包水位控制方式的基础上，采用模糊控制策略对内、外串级回路的PI控制参数进行分区域调整，强调了PI参数在被控参量处于不同范围时的分离作用，同时内、外控制回路采用异步控制方式，浙江大学硕士学位论文从而有效地减小了被控参量的调节时间，提高调节精度，使水位波动控制在△为士12~范围内。
