9. PID auto-tuning of this controller 

In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be made 

to fluctuate to obtain an optimal value. One of 3 types of fluctuation below is automatically selected. 

Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed at or near room   
temperature. Therefore auto-tuning might not finish normally.
