摘　　要：为了优化同步磁阻电机的驱动控制性能,设计了一种新型的同步磁阻电机无模型预测电流控制策略。无模型预测电流控制较之传统的模型预测电流控制的主要优点是其无需使用特定的电机模型,不依赖于电机参数,也无需进行反电动势估计。同时,新型无模型预测电流控制方案设计时有效避免了每个采样周期2次电流测量导致的电流尖峰和电流变化更新停滞降低预测性能的问题。新方案简单易行,无需使用脉宽调制技术。最后,对比试验结果验证了新型控制策略具有较优的控制性能。In order to optimize the drive control performance of synchronous reluctance motor,a novel model-free predictive current control strategy for synchronous reluctance motor was designed. The main advantage of model-free predictive current control over conventional model predictive current control was that it did not require the use of a specific motor model,did not rely on motor parameters,and did not require back-EMF estimation. At the same time,the new model-free predictive current control scheme was designed to avoid the problem of current spikes caused by two current measurements in each sampling period and the current variation update stagnation to reduce the prediction performance. The new solution is simple and easy to realize,and no need to use pulse width modulation. Finally,the comparison test results verify that the new control strategy has better control performance.
