Abstract: A way in theory to solve problems about temperature sensor
location, thermal actuator variable selection and actuator input
pairing up with thermal deformation of key point output for
precision machine via singular value decomposition analysis
method is tended to find. The ouptut dominant direction method
to select temperature sensor location, a singular array method
to pair input up with output and the minimum condition number
method to determine the optimal thermal actuator control
variables are presented. An application of thermal regulation
control method has illustrated the feasibility and practicality
of the new methods.
Key words: Singular
value decomposition Thermal deformation Precision machine
