基于复合谐波电压ADALINE的永磁同步电机驱动系统谐波抑制策略研究
Research on harmonic suppression strategy in permanent magnet synchronous motor drive system based on composite harmonic voltage ADALINE
摘要
Abstract
To address the issue of current harmonics in the output of the automotive permanent magnet synchronous motor (PMSM) drive system,with the consideration of nonlinear factors within the motor drive system such as the inverter,time-varying parameters of the permanent magnet synchronous motor,control algorithm delays,and measurement from current sensors,this paper proposes a method for suppressing PMSM current harmonics based on composite harmonics voltage ADALINE.First,a nonlinear model for the PMSM drive system,encompassing the driving inverter,is built to obtain the theoretical harmonic voltage.Then,the primary current harmonic components in the dq coordinate system are extracted,and the product of the current harmonic components and the corresponding impedance is obtained to collect the harmonic voltage.The collected harmonic voltage,combined with the theoretical harmonic voltage,serves as the input vector for the linear neural element ADALINE.The adaptive adjustment of weights is achieved using the least mean square algorithm.The output vector of the linear neural element is utilized as feedforward compensation voltage to achieve the suppression of current harmonics.Simulation validation is conducted to assess the impact of four main nonlinearity factors,demonstrating the effectiveness of the proposed composite voltage in suppressing harmonic currents,particularly under low-load conditions.关键词
