Description: The clean energy future that would lie ahead for the world is solar energy. The use of solar energy, principally PV, for different applications, and mainly grid connected, is well suited to most of the rural areas due to the lack of electrification. In this paper we proposed a strategy for optimizing the performance of a grid-connected photovoltaic power system. For this, we opted for an MPPT control method based on the fuzzy logic controlled. The control and improving of the performance of a voltage source inverter for grid connected photovoltaic (PV) systems, we proposed to use a modern technique which is called Direct Power Control. Simulations of the proposed approach give interesting results compared to the existing control strategies in this field. The model of the proposed system is simulated by MATLAB / Simulink Platform: |

Description: 数据采集监测计算伴随着微型计算机技术的快速发展，通过计算机处理，系统将采集的模拟信号转变成数字信号，得出数据，这些采集到的实时数据反映着不同的运行状态，并可以接收运行需要发出的各种命令。在各个领域中，不论是简单到复杂还是从表面到深入，数据采集系统的身影几乎无处不在，所以本课题的研究有着广阔的前景和经济价值，自二十世纪50年代到70年代以来，人们见证了数据采集系统的诞生与发展，从初步认可到逐渐分类，随着微型机的反正也诞生了许多性能优良的数据采集系统，但是在计算机普及之后，数据采集系统发生了巨大发展，然而数据采集系统需要的是不断地测试和完善系统的各项功能，如实时采集、进行记录、反应故障等，整个性能的优劣将受到数据采集的性能特点直接影响，足可见数据采集系统的重要性，因此对于数据采集系统需要不断完善和提升，是今后发展的一个主要方向[1]。(The ongoing developing of information technologies, in many areas, such as communication, control and monitoring, etc., the signal processing technology is becoming more and more widely applied to computer, the analog acquisition and processing in modern industrial control and research. The reliable operation of power system substation, especially the problem of remote monitoring unmanned substations, the merits of the entire property will be subject to the performance characteristics of the data collected directly affect, enough to see the data the importance of the system of acquisition.)

Description: 位置检测装置作为数控机床的重要组成部分，其作用就是检测位移量，并发出反馈信号与数控装置发出的指令信号相比较。光电编码器就是一种旋转式位置传感器，在现代数控伺服系统中广泛应用于角位移或角速率的测量。目前生产和使用的数控机床大多采用的是半闭环控制方式，大多数的系统生产厂家均将位置编码器内置于驱动电机端部，间接测量执行部件的实际位置或位移。(The position detection device is an important part of the CNC machine tool, its function is to detect the displacement and send the feedback signal to compare with the command signal produced by the numerical control device. Photoelectric encoder is a rotary position sensor, widely used in modern CNC servo system for angular displacement or angular rate measurement. At present, most of the CNC machine tools used in production and use are semi closed loop control. Most of the system manufacturers have put the position encoder in the end of the drive motor to indirectly measure the actual position or displacement of the executing parts.) Platform: |
