孵化环境温湿度监控系统设计
说明： 如果要将此应用项目移植到开发板上，只需要根据此项目的电路图修改管脚，改成我们开发板对应的管脚上。温湿度传感器使用的是DHT11，所以数据口按照原理图内接。温度传感器接口也需要修改成我们开发板对应的接口(If you want to transplant this application project to the development board, you only need to modify the pins according to the circuit diagram of this project and change it to the corresponding pin of our development board. The temperature and humidity sensor uses DHT11, so the data port is internally connected according to the schematic diagram. The temperature sensor interface also needs to be modified to the corresponding interface of our development board)

Dead-time-Compensation-
针对感应电机矢量控制系统，提出了一种可以同时补 偿死区误差电压并消除零电流钳位现象的死区补偿方法。在分析影响死区效应的因素以及等效死区时间表达式的基础上，采用平均死区时间补偿法，在两相静止轴系中对等效死区时间产生的误差电压进行了补偿。为了提高电流极性检测的准确性，利用旋转轴系中的励磁电流和转矩电流分量经过 坐标反变换，判断电流在两相静止轴系所处的扇区来决定需 要施加的补偿电压。(A dead—time compensation strategy is presented to compensate dead time elTor voltage and eliminate zero·-
current clamping effect for vector controlled induction motor
drive system．The factors influencing dead·time effect are
analyzed,and expression of equivalent dead time is deduced.Average dead·time compensation technique is adopted to
compensate error voltage at two—axes stationary frame．To
improve accuracy of current polarity detection，components of magnetizing current and torque current are transformed into two-axes stationary frame．Therefore，compensating voltage
vector Can be determined according to the sector where the current vector locates．)

某贸易中心共10层，设有载客电梯1部。为了处理问题的方便，有以下的限定条件： （1） 电梯的运行规则是：可到达每层。 （2） 每部电梯的最大乘员量均为K人（K值可以根据仿真情况在10~20人之间确定）。 （3） 仿真开始时，电梯随机地处于其符合运行规则的任意一层，为空梯。 （4） 仿真开始后，有N人(>20人)在该国际贸易中心的1层，开始乘梯活动。 （5） 每个人初次所要到达的楼层是随机的，开始在底层等待电梯到来。 （6） 每个人乘坐电梯到达指定楼层后，再随机地去往另一楼层，依此类推，当每人乘坐过L次（L值可以根据仿真情况在3~10次之间确定）电梯后，第L+1次为下至底层并结束乘梯行为。到所有人结束乘梯行为时，本次仿真结束。 （7） 电梯运行速度为S秒/层（S值可以根据仿真情况在1~5之间确定），每人上下时间为T秒（T值可以根据仿真情况在2~10之间确定）。 （8） 电梯运行的方向由先发出请求者决定，不允许后发出请求者改变电梯的当前运行方向，除非是未被请求的空梯。(a total of 10 layers, with a passenger elevator. To address the issue of convenience, have the following qualifications : (a) lift the operating rules is : can be reached on each floor. (2) each lift crew of the largest volume of all K (K value can be based on the simulation of the 10 to 20 between determined). (3) simulation at the beginning, randomly located in the lift line with its rules of operation arbitrary layer of air staircase. (4) simulation began, a N (gt; 20) at the International Trade Center in one layer, started by ladder activities. (5) Each person must first reach the floors are random, in the bottom wait for the elevator arrived. (6) Each person taken the lift arrived at the designated floor and then another random foot to the floor, and so on, when each rode L (L value c)
