摘要： A method of minimizing the cold start delay and impact fatigue of an actuator includes calibrating the actuator by initially raising the temperature to a desired operating temperature through induction heating of the actuator rod. Additionally, a control system for a magnetostrictive actuator includes a rod of magnetostrictive material, a solenoid coil wrapped at least once around said rod, and a controller operatively connected to said solenoid coil wherein the controller detects an impact of the rod with another surface and adjusts the operation of the actuator to minimize the potential for additional future impacts. The rod may be segmented and include end caps to further reduce the potential for impact fatigue.
