經典的電機的速度PID控制源程序(運用了TI的DMC)

ID:276077 · 發表于 2018-1-15 10:42

這是使用了TI芯片的一個經典的電機控制PID程序，初學者可以看看學習一下電機控制的理論。大神也可以提出自己的意見和見解哦。

單片機源程序如下:

#include "2407c.h"
#include "2407e.h"
#include "Pid_reg1.h"
#include "display.h"

#include "Postion_reg.h"

&pid0, //Point to PID calc
0, //Speed Freeback
0x01ff, //Init speed
0x100, //Speed
(void (*)(int))EVA_PWM1_Init, //Function for init
(void (*)(int))EVA_PWM1_Updata //Function for updata
};
POSTIONPID postion0={
&speed0, //Speed Reg
0, //Absolute postion
0xfffff, //Reference input
0, //Free back input
0, //Postion Reg Output
0x10, //Speed

-1023, //Min Speed
0, //E1
0, //E2
130, //Kp
250, //Ki
0, //Kd
