  • 多功能数字时钟
    基于ARM Cortex-M4F(TM4C123)单片机 ,编程控制TM4C123微控制器的RTC 模块,实现一个简易的数字时钟,具有多种功能 ?【功能】 ?(1)UART输出当前时间信息,UART可设置日期和时间,设置方法自定; ?(2)可通过UART 设置/查询闹钟,定闹时间到,从UART输出提醒; ?(3)在液晶屏上显示日期和时间信息(中文); ?(4)可使用实验板上的K1-K4按键修改日期和时间,设置方法自定; ?注:该题依赖于“3”,需先完成“3”才可做该题 ?(5)农历功能,农历自动跟踪阳历的变化; ?(6)24节气功能(Based on ARM Cortex-M4F (TM4C123) MCU, the RTC module of TM4C123 microcontroller is programmed and controlled to realize a simple digital clock, which has many functions. (function) (1) UART output the current time information, UART can set the date and time, set the method to set itself. (2) the alarm clock can be set / inquired by UART, and the time is up until UART is output. (3) display date and time information on LCD screen (Chinese); (4) you can use the K1-K4 button on the experiment board to change the date and time, and set the method to set it. Note: the question depends on "3", and it is necessary to finish "3" first. (5) the function of the lunar calendar, and the lunar calendar automatically tracks the changes of the solar calendar. (6) the function of 24 throttle)

    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.)
