摘要
深入分析了以定子电流、转子磁链为状态变量的异步电机状态观测器方案,提出一种异步电机状态观测器的极点配置方法,系统给出观测器的设计过程;并给出定子电阻、转子电阻和速度的自适应率.仿真研究和现场实验表明,该方案对电机参数变化的鲁棒性好,磁链观测精度高,收敛速度快.基于该状态观测器方可实现高性能的无速度传感器运行.
This paper presents a completely analysis for the state observer whose state variables are stator currents and rotor fluxes and a new poles designation method is proposed and a detailed process of designing is also described.Then the adaption laws for stator resistant and rotor resistant and speed are given.The proposed method is verified with simulation and experiments.
