Abstract

This paper proposes the calculation method of the reference torque to realize high-speed operation for interior permanent magnet synchronous motor drives with direct torque control (DTC). In DTC, high-speed operation can be realized with limiting reference torque including maximum torque per flux (MTPF) control. However, the optimal MTPF control is difficult for DTC. Thus, this paper proposes the calculation method of the limiting torque considering the stable control for DTC, and uses the asymptote of MTPF locus. The proposed method is validated in simulations and experiments.
在直接转矩控制的IPMSM驱动器中高速操作的渐近MTPF控制
提出了采用直接转矩控制(DTC)的内置式永磁同步电机实现高速运行的参考转矩计算方法。在直接转矩控制中,通过限制参考转矩,包括最大转矩/磁通(MTPF)控制,可以实现高速运行。然而,对于DTC来说,MTPF的最优控制是一个难题。因此,本文提出了考虑稳态控制的直接转矩的计算方法,并采用了MTPF轨迹的渐近线。仿真和实验验证了该方法的有效性。
