Abstract

This paper presents an adaptive observer-based approach to improve the speed-tracking control performance in the permanent magnet synchronous motor drive system with unknown load torque and mechanical parameters. An adaptive observer is designed to estimate the load torque and the mechanical parameters. Using the stability analysis result of Popov theory, the proposed observer is restructured. Then, an adaptive torque feed-forward control is introduced to improve the system dynamic performance. The effectiveness of the proposed schemes is illustrated both by simulation and by experimental results.
