摘要

摘要: 水下航行器永磁同步电机(PMSM)在低速运行时需要具有快速的转矩电流动态响应能力来提高控制系统的操控性能。文中针对传统PMSM低速最大转矩电流比(MTPA)控制方法动态响应性能不佳的问题, 提出了一种MTPA低速高动态响应控制方法。该方法通过在速度外环使用分段式拟合算法、电流内环使用预测控制实现MTPA控制, 并提出了一种根据电机参数自动分段的算法。仿真和实验结果表明, 文中所提控制方法具有更快的动态响应速度。

Abstract: The permanent magnet synchronous motor(PMSM) used in undersea vehicles must have a fast torque current dynamic response capability to improve the control performance of the control system when running at low speed. Aiming at the poor dynamic response performance of the traditional low-speed maximum torque per Ample(MTPA) control method of PMSM used in underwater vehicles, this paper proposes a low-speed MTPA high-dynamic response control method. This method achieves MTPA control using a segmented fitting algorithm in the outer speed loop and predictive control in the current inner loop, and an algorithm for automatic segmentation based on motor parameters is proposed. Simulation and experimental results demonstrate that the control method proposed in this study has a faster dynamic response speed.
