摘要: A system for maintaining thermal stability of a motion stage driven by a motor comprises a motion current generator operative to produce a motion current to drive the motion stage to move and a thermal current generator operative to produce a thermal current to dissipate heat in the motion stage for controlling a temperature of the motion stage without producing corresponding movement of the motion stage. A summation controller is operative to combine the motion current with the thermal current, and to produce a combined current output to the motor.
