永磁同步电机高频注入启动代码

永磁同步电机高频注入启动的代码如下：

#include "stm32f10x.h"

#define PWM_FREQ    20000   // PWM频率
#define PWM_PERIOD  (72000000 / PWM_FREQ - 1)  // PWM周期
#define PI          3.1415926f  // 圆周率
#define FREQ        30.0f   // 电机基波频率
#define AMP         0.1f    // 电机基波电流幅值

float theta = 0.0f; // 角度

void TIM1_UP_IRQHandler(void)
{
    static float phase = 0.0f;

    if (TIM_GetITStatus(TIM1, TIM_IT_Update) != RESET)
    {
        TIM_ClearITPendingBit(TIM1, TIM_IT_Update);

        // 计算电流
        float current = AMP * sinf(phase);

        // 更新占空比
        uint16_t duty = (uint16_t)((current / 3.3f) * PWM_PERIOD);

        // 设置PWM占空比
        TIM_SetCompare1(TIM2, duty);

        // 更新相位
        phase += 2.0f * PI * FREQ * 0.0001f;

        if (phase > 2.0f * PI)
        {
            phase -= 2.0f * PI;
        }
    }
}

int main(void)
{
    // 初始化PWM
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_AFIO, ENABLE);
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);

    GPIO_InitTypeDef GPIO_InitStructure;
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_TimeBaseStructure.TIM_Period = PWM_PERIOD;
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);

    TIM_OCInitTypeDef TIM_OCInitStructure;
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 0;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC1Init(TIM2, &TIM_OCInitStructure);

    TIM_Cmd(TIM2, ENABLE);

    // 初始化定时器1
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);

    TIM_TimeBaseStructure.TIM_Period = 7199;
    TIM_TimeBaseStructure.TIM_Prescaler = 999;
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

    TIM_ITConfig(TIM1, TIM_IT_Update, ENABLE);

    NVIC_InitTypeDef NVIC_InitStructure;
    NVIC_InitStructure.NVIC_IRQChannel = TIM1_UP_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    // 启动定时器1
    TIM_Cmd(TIM1, ENABLE);

    while (1)
    {
        // 循环等待中断
    }
}

这是一个使用STM32F10x系列单片机进行永磁同步电机高频注入启动的简单示例代码。在该代码中，使用了定时器1定时器中断，并在定时器中断中计算电流并更新PWM占空比，从而实现对电机的高频注入启动。
