標(biāo)題: DSP2833電機(jī)控制PWM程序
電機(jī)控制

DSP2833源程序如下:
  1. #include "DSP2833x_Device.h"     // DSP2833x Headerfile Include File
  2. #include "DSP2833x_Examples.h"   // DSP2833x Examples Include File
  3. #include "clarke.h"
  4. #include"park.h"
  5. #include"ipark.h"
  6. #include"svgen_dq.h"
  7. #include"DSP2833x_EPwm.h"
  8. #include"IQmathLib.h"
  9. #include"F28335_epwm.h"
  10. Uint16    *ExRamStart = (Uint16 *)0x100000;
  11. //void EPwmSetup();
  12. #define SYSTEM_FREQUENCY 150
  13. #define ISR_FREQUENCY 10
  14. Uint16  i;

  16. float Vd_testing = 0;                        //直軸電壓標(biāo)幺值
  17. float Vq_testing = 0.25;                 //交軸電壓標(biāo)幺值
  18. float Id_ref = 0;                                //直軸電流給定，標(biāo)幺值
  19. float Iq_ref = 0.025;  //交軸電流給定，標(biāo)幺值

  21. //volatile _iq speed_ref =_IQ(0.01);                 //速度給定，標(biāo)幺值 電機(jī)速度=12000*speed_ref
  22. //volatile _iq position_ref =_IQ(0.0);                 //位置給定，標(biāo)幺值 位置給定=50*position_ref

  24. extern PWMGEN pwm1;


  27. void main(void)
  28. {
  29. // Step 1. Initialize System Control:
  30. // PLL, WatchDog, enable Peripheral Clocks
  31. // This example function is found in the DSP2833x_SysCtrl.c file.
  32.    InitSysCtrl();

  34. // Step 2. Initalize GPIO:
  35. // This example function is found in the DSP2833x_Gpio.c file and
  36. // illustrates how to set the GPIO to it's default state.
  37. // InitGpio();  // Skipped for this example
  38.    InitXintf16Gpio();        //zq

  40. // Step 3. Clear all interrupts and initialize PIE vector table:
  41. // Disable CPU interrupts
  42.    DINT;

  44. // Initialize the PIE control registers to their default state.
  45. // The default state is all PIE interrupts disabled and flags
  46. // are cleared.
  47. // This function is found in the DSP2833x_PieCtrl.c file.
  48.    InitPieCtrl();

  50. // Disable CPU interrupts and clear all CPU interrupt flags:
  51.    IER = 0x0000;
  52.    IFR = 0x0000;

  54. // Initialize the PIE vector table with pointers to the shell Interrupt
  55. // Service Routines (ISR).
  56. // This will populate the entire table, even if the interrupt
  57. // is not used in this example.  This is useful for debug purposes.
  58. // The shell ISR routines are found in DSP2833x_DefaultIsr.c.
  59. // This function is found in DSP2833x_PieVect.c.
  60.    InitPieVectTable();

  62.    IER |= M_INT3;

  64. // Enable EPWM INTn in the PIE: Group 3 interrupt 1-6
  65.    PieCtrlRegs.PIEIER3.bit.INTx1 = 1;


  68. // Enable global Interrupts and higher priority real-time debug events:
  69.    EINT;   // Enable Global interrupt INTM
  70.    ERTM;   // Enable Global realtime interrupt DBGM

  72. // Interrupts that are used in this example are re-mapped to
  73. // ISR functions found within this file.

  75. // Step 4. Initialize the Device Peripheral. This function can be
  76. //         found in DSP2833x_CpuTimers.c
  77.   // InitCpuTimers();   // For this example, only initialize the Cpu Timers

  79. // Configure CPU-Timer 0, 1, and 2 to interrupt every second:
  80. // 150MHz CPU Freq, 1 second Period (in uSeconds)

  82.    //ConfigCpuTimer(&CpuTimer0, 150, 1000000);
  83.    //ConfigCpuTimer(&CpuTimer1, 150, 1000000);
  84.    //ConfigCpuTimer(&CpuTimer2, 150, 1000000);
  85. //        StartCpuTimer0();
  86.   
  87. //        EPwmSetup();
  88.         pwm1.init(&pwm1);

是不是得用這種硬件來做啊
