一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算， 而将所有参数全部用整数，运算到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可 大大提高运算速度，根据控制精度的不同要求，当精度要求很高时，注意保留移位引起的“余数”，做好余 数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。 (A typical PID process, using the microcontroller as a control cpu, make some simplification, the specific PID parameters must be determined experimentally by a specific object. As the chip processing speed and ram resource constraints, generally do not use floating-point operations, and all parameters of all integers, and divided by an operator to the last N-th power of 2 data (the equivalent of the shift) for a similar fixed-point operations, can greatly improve the speed of operation, according to the different requirements of precision control, when high precision, attention to retain the shift caused by the " remainder" and on the remainder of compensation. This procedure is commonly used basic structure pid algorithm, does not include input and output processing section.)

首先定义一个高斯白噪声，然后在正弦信号中添加白噪声，再对带噪声的正弦信号进行平均值滤波(First, a Gauss white noise is defined, then the white noise is added to the sinusoidal signal, and then the average filtering of the sinusoidal signal with noise is filtered)

说明：  蚂蚁所在的环境是一个虚拟的世界，其中有障碍物，有别的蚂蚁，还有信息素，信息素有两种，一种是找到食物的蚂蚁洒下的食物信息素，一种是找到窝的蚂蚁洒下的窝的信息素。每个蚂蚁都仅仅能感知它范围内的环境信息。环境以一定的速率让信息素消失。(The environment where ants are located is a virtual world, including obstacles, other ants, and pheromones. There are two kinds of information. One is food pheromone spilled by ants who find food, and the other is the pheromone of nest scattered by ants who find nest. Each ant can only perceive the environmental information in its scope. The environment makes pheromones disappear at a certain rate.)
