提出了一种简化的基于模糊逻辑的内置式永磁同步电机(IPMSM)速度控制器，以获得具有固有非线性的定子电流的最大转矩/安培(Mtpa)。阐述了与电机控制应用有关的模糊逻辑算法的基本原理。研究发现，用于IPMSM驱动的简化模糊速度控制器与非简化的基于模糊的算法相比，具有更简单和更少的计算密集型实现，从而保持较高的性能标准。与传统的d轴电流为零的IPMSM控制相反，推导了d轴电流的非线性表达式，并将其纳入最大转矩运行的控制算法中。通过仿真和实验验证了所提出的基于简化模糊逻辑控制器(FLC)的带MTPA的IPMSM驱动器在动态运行条件下的有效性。带有MTPA的简化FLC被发现对于IPMSM驱动器中的应用是健壮的。完整的矢量控制方案是在实验室1马力IPM同步电机中使用数字信号处理器(DSP)控制器板DS 1102实时实施的。
This paper presents a simplified fuzzy-logic-based speed controller of an interior permanent-magnet synchronous motor (IPMSM) drive for maximum torque per ampere (MTPA) of stator current with inherent nonlinearities of the motor. The fundamentals of fuzzy logic algorithms as related to motor control applications are illustrated. A simplified fuzzy speed controller for the IPMSM drive has been found to maintain high performance standards with a much simpler and less computation-intensive implementation than a nonsimplified fuzzy-based algorithm. Contrary to the conventional control of IPMSM with d-axis current equal to zero, a nonlinear expression of d-axis current has been derived and subsequently incorporated in the control algorithm for maximum torque operation. The efficacy of the proposed simplified fuzzy-logic-controller (FLC)-based IPMSM drive with MTPA is verified by simulation as well as experimentally at dynamic operating conditions. The simplified FLC with MTPA is found to be robust for applications in IPMSM drives. The complete vector control scheme is implemented in real-time using a digital signal processor (DSP) controller board DS 1102 in a laboratory 1-hp IPM synchronous motor.
