摘要:
为了研究感应电机无速度传感器磁场定向控制系统,基于变结构控制和自适应控制理论,提出一种双滑模面变结构模型参考自适应观测器,用于感应电机的转速辨识。该方法将变结构和模型参考自适应系统进行有机的整合,选择转子磁链电压模型和电流模型分别作为参考模型和可调模型,采用两模型输出的偏差构造了两个滑模面,利用代数计算方法获得转子估计速度。理论分析和仿真结果表明:所提出的感应电机转速辨识方法具有较高的转子磁链观测准确度,改善了转速估计的动静态性能;对于参数变化具有很强的自适应能力,同时算法简单,适用于实时应用。
Abstract:
A novel strategy of double-manifold variable structure model reference adaptive system(VS-MRAS) observers for the speed identification of a sensorless field-oriented vector controlled induction motor drives was presented.This observers combined MRAS with variable structure control,selected the voltage model of rotor fluxes as the reference model and the current model of rotor fluxes as the adjustable model,and formulated double-manifold according the output errors of two models.In the presented observers,th...
