This study presents a maximum torque per ampere (MTPA) control method for a mono inverter dual parallel (MIDP) surface-mounted permanent-magnet synchronous motor (SPMSM) drive system. The multimotor drive system has been extensively studied, because it can drive moreover two motors using only one inverter, reducing the costly power conversion circuit. However, existing studies concerning MIDP permanent-magnet synchronous motor drive systems focus on stabilizing the system, and studies regarding efficiency optimization are difficult to find. Some studies have shown the efficiency-optimizing method, but implementing is challenging because of the complicated calculations and algorithm. The proposed control method can achieve efficiency-optimizing operation using the angle difference controller. The angle difference controller controls the angle difference of two motors to an optimal value. Furthermore, the optimal angle difference of two motors can be easily obtained regardless of parameter errors, using the perturbation and observation algorithm. The proposed MTPA strategy is verified by performing simulations using matlab Simulink and applying the method to an actual MIDP SPMSM drive system.

使用角度差控制器和P&O算法的MIDP SPMSM驱动系统的MTPA控制方法

本研究提出了单逆变器双并联 (MIDP) 表面贴装永磁同步电机 (SPMSM) 驱动系统的最大每安培转矩 (MTPA) 控制方法。多电机驱动系统已被广泛研究,因为它可以仅使用一个逆变器驱动两个电机,减少昂贵的功率转换电路。然而,现有的关于MIDP永磁同步电机驱动系统的研究主要集中在稳定系统上,关于效率优化的研究很难找到。一些研究表明了效率优化方法,但由于计算和算法复杂,实施起来具有挑战性。所提出的控制方法可以使用角度差控制器实现效率优化操作。角度差控制器将两台电机的角度差控制到一个最佳值。此外,无论参数误差如何,使用扰动和观察算法都可以轻松获得两个电机的最佳角度差。所提出的 MTPA 策略通过使用执行模拟来验证matlab Simulink 并将该方法应用于实际的 MIDP SPMSM 驱动系统。
