Accurate Control of Position by Induction Heating-Produced Thermoelasticity

An alternative possibility of highly accurate control of position is suggested, realized by a simple device with a cylindrical dilatation element that works on the principle of thermoelasticity produced by induction heating. The paper describes the device, presents its complete mathematical model in common with the methodology of its numerical solution, and also the algorithm of the control process. The theoretical analysis is illustrated by a typical example, whose results are discussed.
