摘要
针对传统的电流型转子磁链观测器、电压型转子磁链观测器以及改进电压型转子磁链观测器各自的优缺点和适用范围,设计了一种由电流型和改进电压型转子磁链观测器组合而成的一种新型转子磁链观测器,并在模型切换过程中采用改进的滞环切换器。对建立的新型观测器的Simulink模型进行仿真,结果表明,新型观测器能够得到较精确的转子磁链观测值。
Aiming at various advantages, disadvantages and applicable scope of traditional current rotor flux observ- er, voltage rotor flux observer and improved voltage rotor flux observer, a new-type rotor flux observer is designed by com- bining current rotor flux observer and improved voltage rotor flux observer, with the improved hysteresis switcher used dur- ing the model switching process. The simulation of Simulink model for new-type observer is performed, and the simulation result shows that the new observer in the paper can work out precise rotor flux observation value.
