摘要
分析了转子电阻和转子时间常数变化对矢量控制系统性能的影响,针对这一影响,设计了一种基于转子磁链模型的磁链混合观测器.经过仿真,结果表明磁链混合观测器能明显抑制电机参数时变带来的影响,提高系统的性能.
Abstract
In this paper,the influence of rotor resistance and rotor time constant variation on the performance of vec-tor control system is analyzed.In order to overcome this influence,hybrid flux observer based on rotor flux model is adopted.The simulation results show that this hybrid flux observer has obvious effect on suppressing the influence of time variation of motor parameters and improving the performance of the system.
