Soft and hard control system.

Project	Soft control	Hard to manipulate
The system for clearance	Small	Big
System friction	Big	Small
The system stiffness	Poor	Good
For structural deformation and temperature change	Sensitive	Not sensitive
Weight	Lighter	Heavier
Maintainability	Different	Good
Cost	Lower	Higher
Production phase	Shorter	Longer
