给出用stm32f103库函数实现单相逆变锁相环控制的程序代码

当实现单相逆变锁相环控制时，您可以使用STM32F103库函数来简化开发过程。以下是一个简单的示例代码，用于实现基本的单相逆变锁相环控制：

#include "stm32f10x.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_tim.h"

// 定义锁相环相关参数
#define KP 0.1
#define KI 0.01

// 定义逆变电压频率和幅值
#define VOLTAGE_FREQUENCY 50 // 50Hz
#define VOLTAGE_AMPLITUDE 100 // 假设为100V

// 定义采样参数
#define SAMPLE_FREQUENCY 1000 // 采样频率为1kHz
#define SAMPLE_PERIOD (SystemCoreClock / SAMPLE_FREQUENCY)

// 定义周期计数器
volatile uint32_t cycleCounter = 0;

// 定义PWM输出计数器
volatile uint32_t pwmCounter = 0;

// 定义锁相环参数
volatile float phase = 0;
volatile float frequency = VOLTAGE_FREQUENCY;

// 锁相环中断处理函数
void TIM2_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET)
    {
        // 清除中断标志
        TIM_ClearITPendingBit(TIM2, TIM_IT_Update);

        // 更新锁相环参数
        float error = phase - TIM_GetCounter(TIM3);
        float increment = KP * error + KI * frequency;
        phase += increment;

        // 更新逆变电压幅值
        uint16_t voltage = (uint16_t)(VOLTAGE_AMPLITUDE * sinf(phase));

        // 更新PWM占空比
        TIM_SetCompare1(TIM4, voltage);
    }
}

// 定时器3中断处理函数
void TIM3_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM3, TIM_IT_Update) != RESET)
    {
        // 清除中断标志
        TIM_ClearITPendingBit(TIM3, TIM_IT_Update);

        // 更新周期计数器
        cycleCounter++;
    }
}

// 主函数
int main(void)
{
    // 初始化系统时钟和外设
    SystemInit();
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2 | RCC_APB1Periph_TIM3, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_AFIO, ENABLE);

    // 配置PA6引脚为TIM3_CH1
    GPIO_InitTypeDef GPIO_InitStructure;
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置TIM2为锁相环定时器
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseStructure.TIM_Period = SAMPLE_PERIOD;
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);

    // 配置TIM3为周期计数器
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseStructure.TIM_Period = 36000; // 假设为1s
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;
    TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);

    // 配置TIM4为PWM输出
    TIM_OCInitTypeDef TIM_OCInitStructure;
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Disable;
    TIM_OCInitStructure.TIM_Pulse = 0;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_High;
    TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Reset;
    TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCNIdleState_Reset;
    TIM_OC1Init(TIM4, &TIM_OCInitStructure);

    // 配置中断
    NVIC_InitTypeDef NVIC_InitStructure;
    NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
    NVIC_Init(&NVIC_InitStructure);

    // 启动定时器和中断
    TIM_Cmd(TIM2, ENABLE);
    TIM_Cmd(TIM3, ENABLE);
    TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE);
    TIM_ITConfig(TIM3, TIM_IT_Update, ENABLE);

    while (1)
    {
        // 假设这里可以进行其他相关操作
    }
}
