Through it the author made a deep study of the satellite attitude control subsystem , verified several sorts of disturbance torques and realized satellite three - axis attitude stabilization control and attitude maneuver under different conditions 本文在simulink下对卫星姿控系统作了比较深入的研究,对各种干扰力矩进行了验证,同时在不同的仿真条件下实现了卫星三轴稳定控制、姿态机动和飞轮的磁卸载。
After that , the building automation system ( bas ) is chiefly discussed , especially the control and work principles of air - conditioning control subsystem and work flow , charging mode and system frame of the car - parking subsystem are chiefly analyzed 然后,论文着重于楼宇设备自动化系统( bas )的分析讨论,特别是深入地分析了空调监控系统的控制原理,工作原理;停车场管理系统的工作流程,收费模式和系统结构。
Second , expatiates the principle of digital signal processing , voltage sinusoid pulse width modulation , voltage space vector pulse width modulation . third , realizes the logical control subsystem and the driven control subsystem , designs and write some programs 然后详细地介绍了dsp芯片,论述了正弦波pwm ( spwm )法、空间电压矢量svpwm控制技术原理,同时设计了基于dsp的交流变频调速的系统硬软件结构。
The main control console takes charge of communicating with users and controlling subsystems . the gps subsystem is used for receiving and disposing gps data . the gsm / gprs subsystem is used for communicating with the monitoring and dispatching center or others 主控平台主要负责与用户进行信息交互,以便控制和管理整个车载导航系统; gps子系统用于接收和处理gps数据; gsm / gprs子系统用于和车辆监控中心或者第三方进行数据通信。
Then , the general composition and operation of the system is explained . a wireless remote measuring and remote control system includes for subsystems , which are central supervision station subsystem , wireless data communication subsystem , remote measuring subsystem and remote control subsystem 然后论述了无线实时遥测遥控系统的一般组成(主控站子系统、无线通信子系统、遥测终端子系统和遥控终端子系统) 、工作原理以及系统的总体设计。
