In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.

On account of the traffic flow with the high complexity and randomicity, we could adopt fuzzy theory and fuzzy control technology without setting up an accurate math model, which can avoid the unideal control effect, brought by inaccurate math model, and also can adapt the real-time control. Therefore, this paper applies the fuzzy theory and fuzzy control technology to research and discuss traffic control.

因为，交叉路口交通流的运行具有高度复杂性和随机性的特点，采用模糊理论和模糊控制技术，可以不需要建立精确的数学模型，这样既可以避免由于被控对象数学模型建立的不准确而导致控制效果不理想，又能够适应交叉路口的实时控制要求。

To in boat letter this kinds of situation, not divide stage course project and for setting up on the each period of stage there aren't thought , stage of control goal, this text has proposed the control goal model of the quality of stage of course of development based on milestone innovativly, model this divide course that information system develop into feasibility analyse , encode , integrate , is it wait for 9 stages to test, and has confirmed the control goal of quality for each stage , has set up two milestones of quality control , navigate letter course stage that information system develop row , is it have achievement may be examined each period of stage to make, a quality goal is controlled , avoid developing the transparency of course and quality control defect not high of visuality like this.

针对中航信的这种情况，受工程项目对过程进行阶段划分并为每个阶段设立阶段控制目标的思想启发，本文创新性地提出了基于里程碑的开发过程阶段质量控制目标模型，该模型将信息系统开发的过程划分为可行性分析、编码、集成、测试等9个阶段，并为每个阶段确定了质量控制目标，设立了两个质量管理的里程碑，将中航信信息系统开发的过程阶段划，使每个阶段都有成果可以检验，都有质量目标进行控制，这样就避免了开发过程透明度和可视性不高的质量管理缺陷。
