Because of various errors caused by dead time, temperature variation of resistance and so on, the speed estimation error is inevitable in the speed sensor-less vector control methods of the induction motor. Especially, the speed control loop becomes unstable at near zero frequency. In order to solve these problems, this paper proposes a novel design of an adaptive observer for the speed estimation. Adding a feedback loop of the error between the estimated and reference fluxes, the sensitivity of the current error signals for the speed estimation and the primary resistance identification are improved. The proposed system is analyzed and the appropriate feedback gains are derived. The experimental results showed good performance in low speed range.
