模糊控制器是一种基于模糊逻辑的控制器,适用于非线性、复杂、不确定、模糊的系统。其主要思想是将输入量和输出量用模糊集合来表示,通过模糊推理和模糊规则来实现控制。
以下是一个使用C语言实现模糊控制器的示例代码:
```c
#include <stdio.h>
// 模糊集合类型定义
typedef struct {
float a, b, c, d;
} fuzzy_set;
// 模糊规则类型定义
typedef struct {
int antecedent1, antecedent2, consequent;
} fuzzy_rule;
// 模糊控制器类型定义
typedef struct {
fuzzy_set input_sets[3]; // 输入模糊集合
fuzzy_set output_set; // 输出模糊集合
fuzzy_rule rules[9]; // 模糊规则
} fuzzy_controller;
// 初始化模糊控制器
void init_fuzzy_controller(fuzzy_controller *fc) {
// 初始化输入模糊集合
fc->input_sets[0].a = 0;
fc->input_sets[0].b = 0;
fc->input_sets[0].c = 1;
fc->input_sets[0].d = 2;
fc->input_sets[1].a = 1;
fc->input_sets[1].b = 2;
fc->input_sets[1].c = 3;
fc->input_sets[1].d = 4;
fc->input_sets[2].a = 3;
fc->input_sets[2].b = 4;
fc->input_sets[2].c = 5;
fc->input_sets[2].d = 5;
// 初始化输出模糊集合
fc->output_set.a = 0;
fc->output_set.b = 0;
fc->output_set.c = 1;
fc->output_set.d = 1;
// 初始化模糊规则
fc->rules[0].antecedent1 = 0;
fc->rules[0].antecedent2 = 0;
fc->rules[0].consequent = 0;
fc->rules[1].antecedent1 = 0;
fc->rules[1].antecedent2 = 1;
fc->rules[1].consequent = 0;
fc->rules[2].antecedent1 = 0;
fc->rules[2].antecedent2 = 2;
fc->rules[2].consequent = 1;
fc->rules[3].antecedent1 = 1;
fc->rules[3].antecedent2 = 0;
fc->rules[3].consequent = 1;
fc->rules[4].antecedent1 = 1;
fc->rules[4].antecedent2 = 1;
fc->rules[4].consequent = 1;
fc->rules[5].antecedent1 = 1;
fc->rules[5].antecedent2 = 2;
fc->rules[5].consequent = 2;
fc->rules[6].antecedent1 = 2;
fc->rules[6].antecedent2 = 0;
fc->rules[6].consequent = 2;
fc->rules[7].antecedent1 = 2;
fc->rules[7].antecedent2 = 1;
fc->rules[7].consequent = 2;
fc->rules[8].antecedent1 = 2;
fc->rules[8].antecedent2 = 2;
fc->rules[8].consequent = 2;
}
// 模糊逻辑运算
float fuzzy_logic(float a, float b, float c, float d, float x) {
if (x < a || x > d) {
return 0;
} else if (x >= b && x <= c) {
return 1;
} else if (x >= a && x < b) {
return (x - a) / (b - a);
} else {
return (d - x) / (d - c);
}
}
// 模糊推理
float fuzzy_inference(fuzzy_controller fc, float input1, float input2) {
float output = 0;
float wsum = 0;
float w;
for (int i = 0; i < 9; i++) {
w = fuzzy_logic(fc.input_sets[fc.rules[i].antecedent1].a,
fc.input_sets[fc.rules[i].antecedent1].b,
fc.input_sets[fc.rules[i].antecedent1].c,
fc.input_sets[fc.rules[i].antecedent1].d,
input1) *
fuzzy_logic(fc.input_sets[fc.rules[i].antecedent2].a,
fc.input_sets[fc.rules[i].antecedent2].b,
fc.input_sets[fc.rules[i].antecedent2].c,
fc.input_sets[fc.rules[i].antecedent2].d,
input2);
output += w * fc.output_set.c;
wsum += w;
}
if (wsum > 0) {
output /= wsum;
}
return output;
}
// 主函数
int main() {
fuzzy_controller fc;
float input1, input2, output;
init_fuzzy_controller(&fc);
printf("请输入两个输入量:\n");
scanf("%f%f", &input1, &input2);
output = fuzzy_inference(fc, input1, input2);
printf("输出量为:%f\n", output);
return 0;
}
```
该代码实现了一个简单的模糊控制器,其中包括输入模糊集合、输出模糊集合和模糊规则。通过输入量和模糊规则进行模糊推理,得到输出量。整个模糊控制器的实现基于C语言。
