1、 Li Qiu is a boy of fifteen and studying in Grade Three at Oak school. His family lives outside the town. His parents have a farm and grow a lot of vegetables on it and they often sell them in the town. These years they've built a new building and bought a tractor, a motorbike,a color television,a fridge and other things.

Two years ago,Li Qiu began to study in a middle school. He does well in all his lessons and now he's becoming more and more interested in science. He likes to try out new ideas and hopes to be an inventor. This term he's learned electricity (电学). He always watches TV carefully. Last Saturday,when he came back home,his parents were working in the fields. He looked at the new color TV for a while. Then he began to take apart (拆) it. Three hours later his mother came in and saw him fixing the TV set. She was surprised and asked,"What are you doing here,Li Qiu?"

"I took apart the TV just now."

"Don't worry about it,Mummy," said the boy "I only want to know how it works." "Have you refixed it together?" asked Mum.

The purpose of making a decision is to establish and achieve organizational goals and objectives. The reason for making a decision is that a problem exists, goals or objectives are wrong, or something is standing in the way of accomplishing them. Thus the decision-making process is fundamental to management. Almost everything a manager does involves decisions, indeed, some suggest that the management process is decision making. Although managers cannot predict the future, many of their decisions require that they consider possible

项目的监测与控制

第十三讲项目的监测与控制 什么是项目控制 计划、监控的比较 项目计划的主要目标是要设定项目目标和方向,分配资源、预见问题以及确定一些激励措施。 在项目的监测和控制阶段,首先要做的工作是指导项目符合目标,就是根据计划对目标和方向进行设定,尽量使项目进展朝着项目计划所确定的目标和方向前进。其次是有效利用资源,进一步提高资源的使用效率。在计划阶段是预见问题、预测问题。在实施阶段是判断问题、纠正问题,对计划要做一些适当变更,使之更好地完成项目目标。在计划阶段我们做出了一些关于团队建设,关于员工激励的方针和措施,在实施阶段就要贯彻和实施这些措施,对员工做出的贡献给予积极的奖励和鼓励。 两者对比如下所示: 与项目控制有关的问题 1.项目特征 项目本身的特征、大小不一样,则项目的控制难度有所区别。如果是开发一个系统,系统结构、复杂程度不同,则采用不同的控制手段。 2.项目团队 团队的经验以及工作技能、熟练程度与项目的监控有很大的关系:如果项目团队成员对项目工作比较熟悉,在实施当中,控制就显得不那么重要,有些工作依据过去的经验就可以开展;如果项目是个全新的工作,过去从来没有过经验,就要对项目进展加以控制和监测。 3.公司文化 公司本身的传统或者工作习惯、组织的稳定性,都与项目控制有关,也就是采用什么样的控制策略、控制手段,与项目特征、项目人员的经验和能力以及组织本身、公司的问题有关。 4.风险管理 在控制当中,有一个很关键、重要的问题就是对项目的风险管理。风险包括: ?Personnel shortfalls个人错误 ?Dynamic requirements需求变化 ?Externally provided components外部因素 ?Real-time performance 实时绩效 ?Development开发 ?Unrealistic estimates不切实际的估算 在项目实施过程中,这些问题都可能显现出来,必须按照过去计划中的一些既定方针采取有效的对策,对新出现的问题采取一些新的应对措施和应急计划。 项目的监测和控制过程 监测的过程 1.评价实际和计划的完成情况 项目是不是按计划完成,有什么偏差?该检查的完成情况包括工期和成本,即成本预算和实际花费是不是相符合。

自动控制系统及应用

1、为什么说转矩控制是运动控制的根本?试用负载特性曲线比较恒转矩、恒功率和风 机、泵类负载的区别。 2、简]述直流PWM 变换器-电动机系统(直流斩波器)原理(画图说明)? 3、试述晶闸管触发整流器为何有失控时间?频率为50Hz 情况下,三相半波整流器的平 均失控时间是多少? 4、对于恒转矩负载,为什么调压调速的调速范围不大?电动机机械特性越软,调速范 围越大吗? 1、某调速系统,min /1500max 0r n =,min /150min 0r n =,额定负载时的速降min /15r n N =?,若不同转速下额定速降不变,则系统能达到的调速范围是多少?系统允许的静差率是多少? 2、某闭环系统开环放大倍数是15时,额定负载下的速降是8r/min ;如果开环放大倍数是30时,速降是多少?同样静差率下,调速范围扩大多少? 3、有一V-M 系统,电动机参数:额定功率2.2kW ,额定电压220V ,额定电流12.5A ,额定转速为1500r/min ,电枢电阻1.2Ω,整流装置内阻1.5Ω,触发整流环节放大倍数为35,要求系统满足调速范围D=20,静差率小于10%。若采用转速负反馈闭环系统,若主电路电感L=50mH ,系统的转动惯量1.6N.m 2,整流采用三相半波,试判断系统是否稳定?如要稳定,闭环系统的开环放大系数应调整为多少? 4、旋转编码器光栅数为1024,倍频系数为4,高频时钟脉冲频率1MHz ,旋转编码器输出脉冲个数和高频时钟脉冲个数均采用16位计数器,M 法和T 法测速时间均为0/01s ,求转速为1500r/min 和150r/min 时的测速分辨率和误差率最大值。 一个转速、电流双闭环调速系统。 已知:1)电动机:kW P N 555=,V U N 750=,A I N 760=,min /375r n N =,电动势系数r V C e min/82.1?=; 2)主回路总电阻Ω=14.0R ,允许电流过载倍数5.1=λ,触发整流环节放大倍数75=S K ,整流装置为三相桥式; 3)电磁时间常数s T l 031.0=,机电时间常数s T m 112.0=,电流反馈滤波时间常数s T oi 002.0=,转速反馈滤波时间常数s T on 02.0=,
