基于c51单片机的滴灌系统，如何用模糊算法设置不同季节对应的滴灌温湿度需求。#
这个要看你怎么设置，现成的代码网上特别多
确定控制变量和输出变量：
在此情况下，您需要确定控制变量是温度和湿度，而输出变量是滴灌系统的工作时间。
确定输入变量：
为了控制滴灌系统的工作时间，您需要确定季节是一个输入变量。因此，您需要确定不同季节的范围和相应的模糊集。
设计模糊控制器：
设计模糊控制器包括三个主要步骤：
a. 模糊化：将输入变量转换为模糊集。
b. 规则库：使用规则库定义模糊控制器的行为。
c. 解模糊化：将模糊输出转换为实际控制信号。
实现算法：
根据您的设计，在C51单片机上实现算法。
// 定义输入变量
int season;
int temperature;
int humidity;
// 定义输出变量
int watering_time;
// 定义模糊控制器
Fuzzy season_fuzzy;
Fuzzy temperature_fuzzy;
Fuzzy humidity_fuzzy;
Fuzzy watering_time_fuzzy;
// 设定模糊集
FuzzySet season_sets[] = {
FuzzySet("Spring", 0, 2, 4),
FuzzySet("Summer", 2, 4, 6),
FuzzySet("Autumn", 4, 6, 8)
};
FuzzySet temperature_sets[] = {
FuzzySet("Low", 0, 10, 20),
FuzzySet("High", 18, 28, 38)
};
FuzzySet humidity_sets[] = {
FuzzySet("Low", 0, 20, 40),
FuzzySet("High", 30, 60, 100)
};
FuzzySet watering_time_sets[] = {
FuzzySet("Short", 0, 10, 20),
FuzzySet("Medium", 15, 30, 45),
FuzzySet("Long", 40, 60, 80)
};
// 设定规则库
FuzzyRule season_rules[] = {
FuzzyRule("IF Spring THEN", &season_sets[0]),
FuzzyRule("IF Summer THEN", &season_sets[1]),
FuzzyRule("IF Autumn THEN", &season_sets[2])
};
FuzzyRule temperature_rules[] = {
FuzzyRule("IF Low THEN", &temperature_sets[0]),
FuzzyRule("IF High THEN", &temperature_sets[1])
};
FuzzyRule humidity_rules[] = {
FuzzyRule("IF Low THEN", &humidity_sets[0]),
FuzzyRule("IF High THEN", &humidity_sets[1])
};
FuzzyRule watering_time_rules[] = {
FuzzyRule("IF Spring AND Low AND Low THEN", &watering_time_sets[0]),
FuzzyRule("IF Spring AND Low AND High THEN", &watering_time_sets[1]),
FuzzyRule("IF Spring AND High AND Low THEN", &watering_time_sets[1]),
FuzzyRule("IF Spring AND High AND High THEN", &watering_time_sets[2]),
FuzzyRule("IF Summer AND Low AND Low THEN", &watering_time_sets[1]),
FuzzyRule("IF Summer AND Low AND High THEN", &watering_time_sets[1]),
FuzzyRule("IF Summer AND High AND Low THEN", &watering_time_sets[1]),
FuzzyRule("IF Summer AND High AND High THEN", &watering_time_sets[2]),
FuzzyRule("IF Autumn AND Low AND Low THEN", &watering_time_sets[0]),
FuzzyRule("IF Autumn AND Low AND High THEN", &watering_time_sets[1]),
FuzzyRule("IF Autumn AND High AND Low THEN", &watering_time_sets[1]),
FuzzyRule("IF Autumn AND High AND High THEN", &watering_time_sets[2])
};
// 初始化模糊控制器
season_fuzzy.init(season_rules, 3);
temperature_fuzzy.init(temperature_rules, 2);
humidity_fuzzy.init(humidity_rules, 2);
watering_time_fuzzy.init(watering_time_rules, 3);
// 实现算法
void fuzzy_control() {
// 获取季节、温度和湿度
season = get_season();
temperature = get_temperature();
humidity = get_humidity();
// 进行模糊化
float season_value = season_fuzzy.fuzzify(season);
float temperature_value = temperature_fuzzy.fuzzify(temperature);
float humidity_value = humidity_fuzzy.fuzzify(humidity);
// 进行模糊推理
float watering_time_value = watering_time_fuzzy.infer(season_value, temperature_value, humidity_value);
// 进行解模糊化
watering_time = watering_time_fuzzy.defuzzify(watering_time_value);
// 控制滴灌系统
control_watering_system(watering_time);
