摘要
提出一种新颖的基于自适应磁链观测器的辨识方法,与传统的配置电机极点方法设计反馈增益矩阵不同的是,它采用鲁棒控制理论和Lyapunov稳定性理论,通过求解线性矩阵不等式,求出观测器的反馈增益矩阵。仿真结果表明,该方法能准确辨识感应电动机的转子时间常数,具有较快收敛性,较高的无差度及鲁棒性的特点。
A novel estimation method based on adaptive flux observer was pointed out. Different with general pole placement, robust control theory and lyapunov stability theory were implyed by solving a linear matrix inequality （LMI） to obtain the gain of the observer. The simulation result demonstrated the rapid converge, the good performance of estimation and the robustness to the variety of parameter.
