Control precision contrast under static conditions.

Control methods	MAX	MEAN	RMS
PID(urad)	8.1872	1.0041	1.6938‘
PID+DOB(urad)	67.8370	27.2953	33.4699
PID+ARC(urad)	9.3568	1.9641	2.8877

1 MAX stands for largest elements in the error.
2 MEAN stands for average deviation of the error.
3 RMS stands for root mean square of the error.
