说明：  看门狗定时器（WDT，Watch Dog Timer）是单片机的一个组成部分，它实际上是一个计数器，一般给看门狗一个数字，程序开始运行后看门狗开始计数。如果程序运行正常，过一段时间CPU应发出指令让看门狗置零，重新开始计数。如果看门狗增加到设定值就认为程序没有正常工作，强制整个系统复位。(Watch dog timer (WDT, watch dog timer) is a component of single chip microcomputer. It is actually a counter. Generally, it gives a number to the watch dog. After the program starts to run, the watch dog starts to count. If the program runs normally, after a period of time, the CPU shall issue an instruction to set the watchdog to zero and start counting again. If the watchdog increases to the set value, the program will not work normally, and the whole system will be forced to reset.)

说明：  机器人独立PD控制 基于重力补偿的PD控制自适应PD控制 机器人鲁棒自适应PD控制(Independent PD control of robot adaptive PD control robot robust adaptive PD control based on gravity compensation)

本程序用于测试实时时钟模块SD2000系列功能之一:四种中断功能 程序功能如下： 1.在SD2000试验板上显示实时时间的小时和分钟? 2./INT1 到指定时刻时输出低电平. 3./INT2输出固定频率32768HZ. 4.测试每分钟边沿中断输出(INT MODE3)和每分钟固定中断输出(INT MODE4)功能-procedures used to test the real-time clock module SD2000 series of functional one : four interrupts functions of the program are as follows : 1. The SD2000 board real-time test of time 2./INT1 hours and minutes to the designated low-level output at the moment. 3./INT2 32768HZ fixed frequency output. 4. testing every minute edge interrupt output (INT MODE3) per minute and fixed interrupt output (INT MODE4) function

说明：  所谓下垂控制就是选择与传统发电机相似的频率一次下垂特性曲线（Droop Character）作为微源的控制方式，即分别通过P/f下垂控制和Q/V下垂控制来获取稳定的频率和电压，这种控制方法对微网中的微源输出的有功功率和无功功率分别进行控制，无需机组间的通信协调，实现了微源即插即用和对等控制的目标，保证了孤岛下微电网内电力平衡和频率的统一，具有简单可靠的特点(The so-called droop control is to select the Droop Character, which is similar to the traditional generator, as the control mode of micro-source. That is to say, the stable frequency and voltage are obtained by P/f droop control and Q/V droop control respectively. This control method controls the active power and reactive power of micro-source output in the micro-grid separately, without the need of communication coordination between the units. It realizes the goal of micro-source plug-and-play and peer-to-peer control, guarantees the unification of power balance and frequency in micro-grid under islands, and has the characteristics of simplicity and reliability.)
