摘要：

This paper proposes a new temperature estimation method in steady state that employs a compensation method for estimating the temperature using a new voltage disturbance observer autotuning resistance (VDOB AR). In the conventional method, the influence of rotor flux variation is eliminated by the estimation system; however, the variation in inductance is not considered. By using the proposed method, inductance variation can be compensated online with the VDOB AR. In addition, the gains of the VDOB AR are turned by the estimated value to compensate for the resistance variation depending on motor conditions. The effectiveness of the proposed method is verified by experiments and the analysis of the factors related to the voltage disturbance.
