Abstract

This paper presents a speed controller for an interior permanent magnet synchronous motor (IPMSM) based on adaptive backstepping method. By using the nonlinear model of IPMSM and backstepping method, the Lyapunov functions are constructed in order to enable the system to have uniformly asymptotic stability and unperturbed controller is designed successfully by adopting the gradual correcting algorithm. The simulation is completed by using MATLAB software. The simulation results show that the designed feedback controller make the close-loop system stable and has better tracking performance.
