Application of Backstepping Control in PMSM Servo System

摘要

The control of permanent magnet synchronous motor (PMSM) is a highly non-linear system. General control methods are generally not ideal. In practice,system stability is a prerequisite factor. Combination of vector control method of coordinate transformation Backstepping Control strategy is proposed in consideration of the stability. It is not only able to achieve permanent magnet synchronous motor system completely decoupled,but also the design method is relatively simple andean achieve very good position tracking.
