摘要：
Rotor flux oriented field orientation control of induction motor without a speed sensor has been the research topic for quite a few years because of various advantages. However, the estimation rotor flux in the low speed range is difficult and motor parameter dependent. The stator resistance variation can cause error in stator and rotor flux calculation especially in the low speed region. In this paper an effective and simple Rizzy-logic based technique is proposed by which the stator resistance can be easily computed online for improvement of the drive performance in the low sped region. This method id simple effective and can be easily implemented with a micro controller or a DSP based system and needs no external signal injection. The simulation results and some experiments very much validate the proposed concept.
