基于激励信号优化设计的PMSM参数辨识
PMSM Parameter Identification Based on Optimized Excitation Signals
摘要
Abstract
This paper aims at solving two major problems,that is,the existing algorithm for the parameter identification of permanent magnet synchronous motor is complex,and the inverters may affect the accuracy of the identification results.According to the principle of least squares,excitation signal uqref are designed respectively to be direction-fixed and rotating ramp signal when identifying the phase winding Rs and the rotor flux amplitude Ψf;and the excitation signal udref and uqref are designed to be direction-fixed step signal when identifying the Ld and Lq inductances of d and q axis.Thereby,the influence of the inverter is eliminated.And with the motor model in dq synchronous rotating coordinate motor model simplified,the identification of Rs,Ψf,Ld,and Lq is completed.According to the theoretical tuning formula and the identification results of Rs and Lq,the tuning of the current loop PI control parameters is completed.The experimental results show that the identification result is close to the true value with small errors,and the experimental current response is close to the theoretic analysis.关键词
