摘要
This paper proposes an analysis of the vector-controlled induction-motor (IM) drive with a novel modelreference adaptive system (MRAS)-type rotor speed estimator in this scheme which stator-current-error-based MRAS is used instead of the rotor-flux-error-based MRAS scheme,an stator-current-error-based MRAS is used for estimate the IM rotor speed,and this is used as feedback signals for the indirect field oriented control technique (IFOC),which is a widely used control method for Induction Motor drive (IM). For improving the dynamic characteristic of the system, it is very improtant for vector control to proceed parameter tuning. Some experimental results based on TMS 320F2812 DSP are provided to verify the proposed system performance in a low speed at no-load and load conditions.
