lcd1602单片机万年历，不开多得的好资料，你看了肯定不会后悔。(Beginners lcd1602)

基于STM32F103VET6的无刷直流电机控制程序和资料还有原理图(Brushless DC motor control procedures)

说明：  avr单片机，给电压通过单片机片内ad转换给到1602显示。里面有电路图和程序(AVR single-chip microcomputer, the voltage is converted to 1602 display through ad in single-chip microcomputer)

买的一块开发板的开发文档、原理图还有PCB板，并且附有PCI9054的驱动程序及上位机测试应用程序，调试时需要安装Windriver。(Development board to buy a piece of the development of documents, there are PCB board schematics, and with the PCI9054 PC drivers and test applications, when the need to install debug Windriver.)

针对多电机同步控制中传统环形耦合 PID 控制存在抗扰动性不强 扰动下同步误差较大等问题， 提出了一种带前馈控制的滑模变结构多电机相邻耦合控制策略， 建立了3 台永磁同步电动机同步控制仿真模 型， 通过 Lyapunov 稳定性理论证明了滑模控制算法的稳定性， 并进行了交变负载 突变负载实验 仿真分析和 实验结果表明， 该控制策略相比传统环形耦合 PID 控制 相邻耦合 PID 控制具有更高的同步精度和更好的抗扰 动性能(Abstract: Aiming at the problem of poor anti-disturbance capability and big synchronization error under disturbance of traditional ring-couple PID control method in multi-axis synchronization control，a sliding mode variable structure with feed-forward control for relative coupling control strategy is proposed． Three Permanent Magnet Synchronous Motor ( PMSM) for synchronized control simulation modl is set up． The stability of the proposed control algorithm is proved according to Lyapunov stability theory． The control strategy is tested by alternating load，and mutant load experiment． Simulation analysis and experimental results show that the presented control strategy has higher synchronization accuracy and better anti-disturbance capability in camparison with the traditional ring-couple PID control and relative-couple PID control．)
