Abstract:

高性能交流驱动系统中,电机磁链位置能否准确获取将影响系统的动态与稳态性能。异步电机全阶模型同时实现了电机转速作为参数的在线辨识以及电机电流与磁链作为状态变量的实时观测。本文将对全阶模型在估计异步电机参数与变量过程中的磁链收敛特性进行研究。由于全阶模型的非线性特性,采用奇异摄动理论,将全阶模型分解为转速辨识模型与磁链观测模型,两个模型在时间尺度上分离,通过分析磁链观测子系统中系统特征值的分布与阻尼特性,研究了磁链观测的收敛性与影响收敛速度的影响因子。研究结果表明磁链系统在中高速的阻尼特性需要改善,并提出了改善收敛性的对策。仿真和实验验证了分析方法的正确性与所提对策的可行性。
