无差拍预测电流控制DPCC（deadbeat predictive current control）具有动态响应快速的优点，近年来受到国内外学者们的广泛关注，相关研究已取得了大量成果。为了提高DPCC低速稳态性能，以永磁同步电机PMSM（permanent magnet synchronous motor）为对象，提出了一种改进的死区补偿方法。首先，分析死区时间及逆变器非线性特性导致的电压误差；然后，利用dq轴电流指令值替代滤波后的电流值，考虑无差拍预测电流控制中存在的一拍延迟，进行了三相电流重构；最后，分析电流极性对电压误差计算的影响，利用改进的正弦型函数替代传统的开关函数并计算补偿电压。对3种DPCC方法进行了实验对比研究，分别为无死区补偿、传统死区补偿及所提改进的死区补偿算法。结果表明：所提算法可以有效消除电流在过零点处的畸变，进一步降低了电流谐波。

Abstract

收起

Deadbeat predictive current control (DPCC) has attracted wide attention of scholars in recent years owing to its advantage of fast dynamic response, and a lot of research results have been achieved. To improve the low-speed steady-state performance of DPCC for permanent magnet synchronous motors (PMSM), a modified dead-time compensation method is proposed. First, the voltage error caused by the dead-time and the nonlinearity of an inverter is analyzed. Second, the d- and q-axis reference currents are utilized to replace the filtered currents, and three-phase current reconstruction is carried out considering the one-step delay in DPCC. Finally, the influence of current polarity on voltage error calculation is analyzed, and a modified sine function is adopted instead of the conventional switching function to calculate the compensation voltage. Three DPCC methods were compared experimentally, i.e., no dead-time compensation, conventional dead-time compensation and the proposed dead-time compensation algorithm. Results show that the proposed algorithm can effectively eliminate the current distortion at the zero-crossing point and further reduce the current harmonics.
