基于代价函数极值搜索的永磁同步电机无传感器模型预测转矩控制

In this article, a cost-function extremum seeking-based model prediction torque control (CES-MPTC) method of permanent magnet synchronous motor with sensorless position estimation is proposed. First, as the predictive torque and flux linkage are the functions of the DQ-axis voltage components, once the partial derivative of the cost function with the DQ-axis voltage components are zero, the extrem...
