A Rotor Time Constant Identification Method with Compensation Algorithm

Abstract

In the vector control the time constant of rotor changes will affect the system, generally required online identification. This paper puts forward a identification method based on model reference adaptive, using popov exceed stable to design a adaptive rate. Analyses identification system by torque effects, and proposes a kind of compensation algorithm, to improve the system robustness. Under the MATLAB/Simulink environment build simulation model to verify the correctness of the algorithm, and points out the advantages of compensation algorithm.
