资源描述This application note shows how to control a permanent magnet synchronous motor (PMSM) with the sensorless field-oriented control (FOC) algorithm, using an ARM® Cortex®-M0-based PSoC 4 device. The FOC algorithm is frequently used in motor control applications because it allows motors to operate with less noise and more stable torque output than other algorithms. Sensorless FOC adds the advantage of reducing the cost due to the absence of rotor position sensors. Sensorless FOC is used in many applications including consumer (air conditioner, refrigerator), industrial (blower, pump), and commercial (elevator, escalator) products.

FPGA DE2开发板  实验2第一部分VHDL硬件语言练习源码 Part II You are to design a circuit that converts a four-bit binary number V = v3v2v1v0 into its two-digit decimal equivalent D = d1d0. Table 1 shows the required output values. A partial design of this circuit is given in Figure 1. It includes a comparator that checks when the value of V is greater than 9, and uses the output of this comparator in the control of the 7-segment displays. You are to complete the design of this circuit by creating a VHDL entity which includes the comparator, multiplexers, and circuit A (d

本系统儿童睡眠温度报警系统设计采用现在流行的STC89C52单片机芯片，配以DS18B20数字温度传感器，无线传输采用FBT-06主从模块。主单片机控制温度传感器DS18B20采集数字温度，并将采集到的数字温度信号与程序中设置的温度阈值进行比较，如果温度在温度阈值范围之内，则在循环中一直执行采集温度，比较阈值等步骤；如果采集的温度超出了设置的温度阈值范围，则主模块利用蓝牙模块进行数据串行通信，从单片机接收到数据后做匹配，如果匹配一致，则从单片机驱动蜂鸣器，实现报警功能。
