摘要：
In this paper the speed tracking control problem for sensorless (nonsalient-pole surface) permanent magnet synchronous motors (PMSMs) with unknown load torque is addressed. Simulation and experimental results are presented for the first nonlinear adaptive control which (i) relies on a closed loop stability proof using nonlinear stability tools; (ii) feeds back stator current and voltage measurements only without using non-robust open loop integration of motor dynamics. Satisfactory performances are obtained in practice in conditions which can be inferred by deeply analyzing the reported theoretical analysis. (C) 2012 Elsevier Ltd. All rights reserved.
