Abstract
A control device that can prevent the deterioration of temperature estimation accuracy in a rotating electric machine due to its aging deterioration is provided. The control device () includes a correction unit () to correct at least one of thermal resistance, heat generation, and thermal capacity, which are physical quantities to build a thermal circuit model (-) covering a thermal circuit of a rotating electric machine (), wherein the correction unit () corrects at least one of the thermal resistance, the heat generation, and the thermal capacity at a measurement position by using measurement information including temperature (T) or thermal flow (U) measured by a sensing unit () at the measurement position in the rotating electric machine ().
