The paper deals with possibilities of precise position control. The main idea is based on usage of thermoelasticity phenomenon. The main part of proposed device is a dilatation element that is inductively heated by alternating current, which leads to its stretching. After reaching the dilatation required, the Joule losses in the system must be reduced on the value corresponding to the total loss of heat. The task represents a triply coupled problem combined with optimization of the time evolution of the field current whose amplitude must vary in time appropriately. The methodology is illustrated by a typical example.
