softwarephaselockedloop
在电网电压频率波动或者三相不平衡的情况下,硬件锁相很难准确检测到基波正序的相位。在结合PWM整流器空间矢量解耦控制算法的基础上,将软件锁相环技术应用在PWM整流器控制系统中,并用仿真和实验验证了该方案的可行性。实验结果表明,该方案解决了电网电压频率波动及三相不平衡时的相位同步等问题,并在工程上具有一定参考价值。(Frequency or voltage fluctuations in three-phase unbalanced case, the hardware lock is difficult to accurately detect the fundamental positive sequence phase. In the space vector PWM rectifier with decoupling control algorithm based on the software used in the PWM rectifier PLL control system, and use simulation and experimental verification of the feasibility. Experimental results show that the solutions to address the voltage and frequency fluctuations of the phase unbalanced three-phase synchronization issues, and the project has a certain reference value.)

TCPIPTutorial
In the TCP/IP protocol suite, TCP is the intermediate layer
between IP below it, and an application above it. Using TCP,
applications on networked hosts can establish reliable
connections to one another. The protocol guarantees in-order
delivery of data from the sender to the receiver
Streams of data called segments are used by TCP peers to
speak to each other. The segments can be quite large, so TCP
breaks up the segments into smaller units of data. These units
are encapsulated in the TCP packet that is passed to the IP
protocol. Each unit of data is assigned a sequence number,
which becomes part of the TCP packet. At the receiving end, the
TCP module uses the sequence numbers in the packet to
reconstruct the user data in the correct order.
