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.)

随着并联机构学理论的日益成熟,并联摇摆台以其大刚度、高精度和重载等优点,广泛应用于机械、航海和航天等领域。其中,以车辆模拟台的应用最为广泛。车辆在行驶过程中由于受到路况等扰动因素的影响,会产生横摇、纵倾、转艏、前冲、横移和升降共6种位姿的运动,而通过六自由摇摆台能将车辆的这些运动真实的再现出来。
本文以项目——六自由度重型摇摆台的研制为依托,在对国内外六自由度摇摆台的研究现状做了比较深入、系统分析的基础上,对车辆重型摇摆台与负载锁定结构进行了分析优化,主要的研究内容如下:
首先,对六自由度重型摇摆台进行运动学建模,分析、优化机构在六种独立姿态及部分耦合位姿情况下支撑杆的运动范围,最终确定了支撑杆合理的转角空间和上下铰链座的结构,提高了机构的运动学、动力学性能。
(With the development of theory of parallel mechanism, parallel plat quickly enters the international market for high stiffness、high precision and heavy load, which is widely used in mechanical、navigation and aviation, etc. Among these parallel plats, the vehicle simulator is the most widely used. Due to the disturbance factors of ups and downs of the different roads, vehicle has 6 degrees of freedom during its traveling movements, such as rolling、pitching、yawing、surging、swaying and heaving that can be simulated in the use of 6-DOF platform.
Based on the project of heavy platform, this paper optimizes the platform and the load locking structure after the in-depth and systematic analysis of 6-DOF parallel plat at home and abroad, the main research contents are as follows:
Firstly, this paper establish the kinematic modeling that is used to analyze the rotating range of the axis belonging to the supporting pole in many traveling conditions, such as one of six movements indepe)

说明: 3) 跨平台文档结构的调整 项目文档是始终贯穿着整个系统的,但由于Windows系统与其他系统如Linux等的文档结构不同,项目的可移植性将会受到限制,因此强调可移植性的本系统中跨平台文档结构的调整是必不可少的,我们预计在这一阶段以Windows 和 Linux为基础出2套相应的代码版本,基础代码部分不变,只是在文档接口及对应的应用工具上做出相应的选择。预计所需时间为二个月,包括平台的移植,接口的研究和开发等(3) cross-platform document the restructuring of the project document is always run through the whole system, but the Windows system and other systems such as Linux and other documents of different structures, the project will be subject to the portability restrictions of the emphasis on portability cross-platform file system structure is essential, we expect at this stage in Windows and Linux based on the 2 versions of the corresponding code, the basis of some of the same code, but in the document application interface and the corresponding tools choices accordingly. Expected time required for months, including platform migration, interfaces, such as research and development)
