可通航水库闸门简易控制系统概述：水库闸门具有如下四重功能，控制蓄水、及时泄洪、控制通航、保证发电。故一个功能完善的水库系统应有实现发电控制（发电闸门，设为一组）、泄洪或供水需要（泄洪供水闸门，设为一组）及维护通航（通航闸门，上下游各一组）等三种功能的闸门系统。本课题拟设计一水库闸门控制系统，通过组合电路与时序电路共同实现一闸门开关控制器，在试验阶段用LED指示灯亮灭来模拟闸门开关
Navigable dam gate control system outlined in the Summary: Reservoir gates have the following four functions to control the storage and timely discharge, control navigation, to ensure power generation. It is a function of the reservoir system should be improved to achieve power control (power gate, as a group), the need for flood or water (flood water gate, as a group) and the maintenance of navigation (navigation gate, a group of the upstream and downstream ), three features of the gate system. Subject to the design of the gate control system of a reservoir, through the combination of circuit and sequential circuit realization of a common gate switch controller, the pilot phase out with bright LED lights to simulate the gate switch (2009-06-19, WORD, 20KB, 下载7次)
本次设计的简易智能电动车，采用AT89S52单片机作为小车的检测和控制核心；采用金属感应器TL-Q5MC来检测路上感应到的铁片，从而把反馈到的信号送单片机，使单片机按照预定的工作模式控制小车在各区域按预定的速度行驶，并且单片机选择的工作模式不同也可控制小车顺着S形铁片行驶；采用霍尔元件A44E检测小车行驶速度；采用1602LCD实时显示小车行驶的时间，小车停止行驶后，轮流显示小车行驶时间、行驶距离、平均速度以及各速度区行驶的时间
The simple design of the smart electric car, car used as a single-chip AT89S52 detection and control of the core the use of metal detectors to detect TL-Q5MC sensors on the road to the metal plates, thereby sending a signal back to the single-chip, so that single-chip microcomputer according to the mode of control car in the regions according to a predetermined speed, and single-chip mode choice can also be controlled in different cars along the S-shaped metal plates only A44E Hall element used car speed detection 1602LCD using real-time display of the time traveling car, car stop, the rotation time to show the car driving, driving distance, average speed and the speed of travel time zone (2009-05-07, WORD, 371KB, 下载25次)
传统无差拍控制应用于UPS 逆变器,存在对系统参数变化的鲁棒性问题。本文提出了一种
新的控制方案—渐近收敛无差拍控制。该方案与传统无差拍控制的区别是,不是将正弦信号作
为参考电压,而是采用当前的输出电压和正弦信号的加权平均作为下一控制周期的目标量
Traditional deadbeat control applies to UPS inverter, the existence of the system parameters change in the robustness of the problem. This paper presents a new control scheme- Asymptotic convergence deadbeat control. The program with the traditional deadbeat control difference is that instead of sinusoidal signal as a reference voltage, instead of using the current output voltage and sinusoidal signal as a weighted average of the next control cycle of target volume (2008-11-28, WORD, 251KB, 下载94次)
几乎所有设备的传导干扰都包含共模噪音和差模噪音，开关电源也不例外。共模干扰是由于载流导体与大地之间的电位差产生的，其特点是两条线上的杂讯电压是同电位同向的；而差模干扰则是由于载流导体之间的电位差产生的，其特点是两条线上的杂讯电压是同电位反向的。
almost all the equipment includes EMI common mode noise and differential mode noise, switching power supply is no exception. Common mode noise is due to current carrying conductor between the earth and the potential of the poor, Its characteristics are two lines of noise voltage is the same with the potential to; while differential mode interference is the result of current-carrying conductor of the potential difference, Its characteristics are two lines of noise voltage potential is the reverse of the same.
