·上传一些无刷电机BLDC的资料，还有几篇直接转矩DTC的控制文章，希望对大家能有帮助。 (原文件名: A New Simulation Model of BLDC Motor With Real Back EMF Waveform.pdf)  (原文件名: A Sensorless Approach to Control of a Turbodynamic.PDF) 

 在集群系统中，负载均衡算法是影响系统性能的关键因素之一。为了进一步提高集群系统的性能，有必要对负载均衡算法进行优化。通过对最小连接算法和DFB（Dynamic Feed-Back）算法的详细分析，提出了一种改进的动态反馈负载均衡算法。该算法通过收集每台服务器的实时性能参数，动态地计算出各服务节点的分配概率，并由此 ...

Industrial systems demand semiconductors that are precise, flexibleand reliable. Linear Technology offers a broad line of high performanceanalog ICs that simplify system design with rugged devices featuringparameters fully guaranteed over the -40°C to 85°C temperature range.We back this up ...

 The MAX17600–MAX17605 devices are high-speedMOSFET drivers capable of sinking /sourcing 4A peakcurrents. The devices have various inverting and noninvertingpart options that provide greater flexibility incontrolling the MOSFET. The devices have internal logiccircuitry that prevents shoot ...

  Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptabl ...

Abstract: Investment in smart meters and smart grid end equipment continues to grow worldwide as countriestry to make their electric delivery systems more efficient. However, as critical as the electric deliveryinfrastructure is, it is normally not secured and thus subject to attack. This article ...

针对目前汽车追尾事件频发问题，提出一种防汽车车前和车后追尾的安全装置设计。该设计以高性能、低功耗的8位AVR微处理器ATmega8L为核心，结合霍尔式车速传感器、激光雷达测距装置和MMA7260QT加速度传感器，能够兼顾车前和车后，摒弃以往设计中只考虑车前或车后单一性缺点，尤其适用于高速、夜晚或新手行车。 Abstract: & ...

介绍一种简单射频识别系统设计。该设计包括阅读器、应答器和线圈3部分。由单片机控制阅读器向应答器发射无线信号，并接收应答器回送的信号，再通过分析回送信号识别物品。阅读器和应答器之间以半双工通信方式通信。 Abstract:  A simple design of radio frequency identification system is given in this paper.T ...

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C ...

The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlledby the I2C-bus. The low ON-state resistance of the switch allows connections to be madewith minimal propagation delay. Any individual A to B channel or combination of channelscan be selected via the I2C-bus, determi ...
