摘要 为避免转子位置角检测误差给永磁同步电动机调速系统带来的不利影响,提高系统的可靠性,提出一种等价于id=0的永磁同步电动机模型预测功率控制方法。该方法通过建立两相静止坐标系下的电机增量模型,使用枚举法对基本电压矢量作用下的电流进行预测,利用采样得到的电压及电流估计反电动势和转子侧瞬时功率值,然后通过功率价值函数选择最优电压矢量。所提方法无需使用高分辨率位置传感器检测转子位置角进行旋转坐标解耦变换,可降低系统的复杂度。电机增量模型无需使用永磁体磁链参数预测电流,降低了算法对电机参数变化的敏感度。实验对比了所提控制方法与直接功率控制的稳态功率波动、转矩波动和暂态响应速度等指标,证明了所提方法的有效性。

Abstract:In order to avoid the adverse effect of rotor position detection error on permanent magnet synchronous motor (PMSM) speed control system and improve the reliability of the system, a model predictive power control method equivalent to the id=0 control method is proposed to improve the reliability of the system in this paper. Through the establishment of a motor incremental model in a two-phase stationary coordinate system, the enumeration method is used to predict the current under the action of the basic voltage vector, The sampled voltages and currents are used to estimate the back electromotive force and the instantaneous power on rotor side. Then, the cost function based on power are established to select the optimal voltage vector. The proposed method does not need to use a high-resolution position sensor to detect the rotor position angle for decoupling transformation of the rotating coordinate, which reduces the complexity of the system. The incremental model predicts currents without using permanent magnetic flux linkage parameters, which reduces the sensitivity of the algorithm to changes in the motor parameters. A comparative study between the proposed method and direct power control were conducted in terms of power ripples, torque ripples and dynamic response. The experimental results verify the effectiveness of the control method.
