摘要
Abstract
The traditional model reference adaptive system (MRAS) take voltage model as a reference model, the performance of the IM drive system at low speeds became worst by influencing initial value and drift problems of the pure integrator in the voltage model and the variation of motor parameters. In order to improve the low-speed performance and robustness of the system, this paper describes a stator current model-based model reference adaptive method to identify the motor speed and rotor flux, and thus constitutes a vector control system. A lot of the system simulations are completed based on Matlab/Simulink simulation platform. The simulation results show that the robustness against changes of the stator and rotor method has good performance at low speeds, and better parameters.关键词
