永磁同步电机优化双矢量无模型预测电流控制
Optimized Dual-vector Model-free Predictive Current Control for Permanent Magnet Synchronous Motor
摘要
Abstract
In the dual-vector model predictive current control,the algorithm is time-consuming due to the traversal to select the optimal voltage vector,and the control performance is susceptible to the influ-ence of model parameter perturbations.To address these issues,an optimized dual-vector model-free predictive current control method was proposed.An ultra-local model was adopted for current predic-tion,utilizing the input and output of the system.Meanwhile,a sliding mode observer was designed to estimate the parameters in the ultra-local model.The method presented in this paper only required three comparisons to select two optimal voltage vectors,and the duty cycle was obtained based on the difference in the quadrature-axis current,without requiring any motor parameters.The simulation re-sults demonstrate the effectiveness of the proposed method.关键词
