用C语言写一个MPPT算法

好的，以下是一个简单的C语言实现的MPPT算法：

#include <stdio.h>

#define VOLTAGE_MAX 18.0
#define VOLTAGE_MIN 10.0
#define VOLTAGE_STEP 0.1
#define CURRENT_MAX 5.0
#define CURRENT_STEP 0.1

float calculate_power(float voltage, float current) {
    return voltage * current;
}

int main() {
    float voltage = VOLTAGE_MIN;
    float current = 0.0;
    float power = 0.0;
    float max_power = 0.0;
    float max_voltage = 0.0;

    while (voltage <= VOLTAGE_MAX) {
        current = 0.0;
        while (current <= CURRENT_MAX) {
            power = calculate_power(voltage, current);
            if (power > max_power) {
                max_power = power;
                max_voltage = voltage;
            }
            current += CURRENT_STEP;
        }
        voltage += VOLTAGE_STEP;
    }

    printf("Maximum power point: voltage = %.2fV, power = %.2fW\n", max_voltage, max_power);

    return 0;
}

这个程序通过枚举所有可能的电压和电流值，计算出每个点的功率，然后找到最大功率点。注意，这只是一个简单的实现，实际的MPPT算法可能会更复杂。
