摘　　要：从异步电动机的定子磁链模型出发 ,应用直接反馈线性化理论实现了异步电动机系统的输入 -输出线性化与解耦。系统分解成转速和磁链两个独立的最简线性子系统 ,实现了转速和磁链的完全解耦。算法简单实用 。This paper presents a direct feedback linearization (DFL) method to achieve input output linearization and decoupling control of induction motor drive system based on stator flux model.The motor speed and flux are decoupled to two independent linear subsystems completely.The simulation results are satisfactory,and show that the dynamic performance of induction motor drive system is improved greatly.This method is simple and practicable.
