Abstract

This work focuses on performance improvements of the stator flux estimation for a direct torque controlled interior permanent magnet (IPM) synchronous motor drive. In this paper, an adaptive sliding observer is presented to estimate the stator flux linkage based on the motor current model. The observer has better dynamic behavior, disturbance resistance and high accuracy estimation ability. The experimental results show that the proposed observer is able to deliver more accurate estimation than open-loop estimator both in the steady state and during transients
