Abstract
The deformation reason of actuator caused by heat conduction and interaction force is analyzed by introducing thermal conduction and spring rigid model combined with structure of micro-mirror actuator
and multiDOF mathematical model for micro-mirror is established.Comparison of simulation
and experimental data show that the constructed model agrees well with experimental results
it can predict input responses characteristics of four actuators.
