摘要:
利用转子磁链电压模型研究转子磁链误差对感应电动机全阶转速自适应转子磁链观测器稳定性影响。通过研究观测器等效误差系统前向通道传递函数正实性,得到观测器在ω1-ωs平面中稳定区域边界方程。提出不含纯积分器的新型转子磁链误差模型,通过分析该模型对线性化等效转速控制系统开环零点分布影响,研究不同工况下观测器稳定区域分布。研究结果表明增大转子磁链误差能够扩大稳定区域,所提出的模型解决了低速再生发电工况时观测器稳定问题,但在低速电动工况时观测器不稳定。仿真结果表明组合应用不同转速自适应律观测器在所有工况下均能稳定。
Abstract:
The rotor flux error affection on the stability of the induction motor full-order speed adaptive rotor flux observer was studied using the voltage model.The positive-real property of the forward path transfer function of the observer equivalent error system was analyzed.Stability domain border equations in ω1-ωs plane were derived.A modified rotor flux error model excluding a pure integrator was suggested.Affection of the modified model on open-loop zeros plots of the linearized equivalent speed...
