摘要

分析了转子参数变化对感应电机矢量控制解耦的影响,提出了一种对感应电机转子参数进行估算的自适应辨识方法。基于Lyapunov稳定性原理,设计转子参数的自适应规律。利用Matlab/Simulink建立了感应电机矢量控制系统下的转子参数自适应辨识模型,仿真验证了方法的正确性,为校正矢量控制系统定向偏差提供了一定的理论和实践参考。%The paper analyzes the influence of rotor parameters changing for the induction motor vector control,and an adaptive identification method for rotor parameters is proposed.Based on Lyapunov stabilization theory,design method of adaptive identification discipline is expatiated.The model of rotor parameters adaptive identification under induction motor vector control is completed using Matlab/Simulink.The simulation results demonstrate the feasibility of the proposed method,and it can be taken as the theory and practice reference for improve the orientation bias for vector control system.
