飞思卡尔pid算法

飞思卡尔pid算法，实现参数显示和调整void main(void) { float display_value; int count=0; pid = &warm; printf("Enter the values of Process point, Set point, P gain, I gain, D gain \n"); scanf("%d%d%f%f%f", &process_point, &set_point,&p_gain, &i_gain, &d_gain); process_point = 30; set_point = 40; p_gain = (float)(5.2); i_gain = (float)(0.77); d_gain = (float)(0.18); dead_band = 2; integral_val =(float)(0.01); printf("The values of Process point, Set point, P gain, I gain, D gain \n"); printf(" %6d %6d %4f %4f %4f\n", process_point, set_point, p_gain, i_gain, d_gain); printf("Enter the values of Process point\n"); while(count<=20) { scanf("%d",&process_point); pid_init(&warm, process_point, set_point); pid_tune(&warm, p_gain,i_gain,d_gain,dead_band); pid_setinteg(&warm,0.0); pid_setinteg(&warm,30.0); pid_bumpless(&warm); display_value = pid_calc(&warm); printf("%f\n", display_value); printf("\n%f%f%f%f",warm.pv,warm.sp,warm.igain,warm.dgain); count++; } }
