Switched systems are widely used in many practical problems, such as switching control of multiple work modes of planes, web switching of electric systems and sampled-data control systems, et, al 切换系统在很多实际工程应用中经常遇到,如飞机的多工作点切换控制,电力系统网络的切换以及多频采样数字系统的控制等。
Each room is equipped with master switch control lighting . please insert the card key in to the slot beside the door to turn on the lights . when leaving the room please remove the card key to turn lights off automatically 房间配有灯光总控制器,将磁卡插入取电器内,灯光便会自动开亮,当您离开房间时,请取出磁卡,灯光便会自动开关。
In view of the character of drum lifting frame, invariable value and switch control hydraulic transmission system, this paper analyzes reappearing controlling character of memory program controlling-predicted control results 摘要针对采煤机滚筒调高机构的特点,即定量、开关式控制液压系统,分析了记忆程控预知控制结果的再现控制的特征。
It improves on preventing the switching control process from oscillation and refusing compensation . the other is optimal switching control of the multi-tap capacitors formulated by nonlinear hybrid integer programming model 为了实现全局优化控制,本文将一个非线性混合整数规划优化控制模型逐次线性化成增量形式后求解,即逐次线性规划法。

These years more and more emphasize have been focused soft-switching control in phase-shifted zvs pwm full-bridge dc / dc converter and more research need to be made . the principles of phase-shifted zvs pwm full-bridge converter are described and analyzed 基于移相控制的零电压脉宽调制dc-dc全桥变换器是软开关控制的一个研究热点,还有许多理论问题需要研究。
The process of switch control is divided into a series of steps : 1, id recognition; 2, application to operate; 3, authorization to the application by remote monitor; 4, field operation 设计中将开关操作过程分为身份验证、现场申请操作、远方监控端授权申请以及现场执行操作等步骤。为此,就必须保证现场的多个控制机与远程监控主机之间远程通信的可靠进行。
The thesis also designs the municipal electricity blackout and alarm circuit, the ac ( air condition ) switching control circuit, the watchdog circuit, the lcd display circuit, real-time clock circuit and the serial communication testing circuit 此外本文还设计了市电停电告警电路、空调开关控制电路、看门狗电路、lcd显示电路、实时时钟电路和串口通讯测试电路。
Intermittent control itself has such character and difficulty as high control flexibility, flexible control strategy, multi-control model, both switch control and simulation control . it presents higher demand on control system 间歇控制本身具有控制柔性度高、控制策略灵活、多种控制方式并存、开关量控制与模拟量控制并重等特点和难点,对控制系统提出了更高的要求。
It would involve switching control of much of the desert country's most fertile region, known as the green mountain, to an agency that would implement state-of-the-art development plans forged by a bevy of consultants, scholars and engineers from abroad 这个计划将会把这个沙漠国家最富有的地区??包括我们已经知道的“绿山”等地??的开发、管理权转交给一个由国外的顾问、学者和工程师组成的机构。
