摘要：

To achieve controllable d-axis and q-axis current performance with inverter switching frequency reduction, an independent cost function model predictive current control (ICF-MPC) is proposed for surface mounted permanent magnet synchronous motor (SMPMSM) drives. First, two independent cost functions are designed for d-axis and q-axis individual current error. Then, a rectangular constraint that satisfies dq-axes current performance is presented to obtain the voltage vector space. Subsequently, a direct selection and calculation method is proposed to obtain the reference voltage vector, based on the principle of balancing current ripple and switching frequency. The proposed ICF-MPC achieves simultaneous optimization of d-axis current performance, q-axis current performance, and switching frequency without weighting factors. The controllable current performance and switching frequency reduction are demonstrated by the experimental results.
