摘要
本文研究了双逆变器绕组感应电机(di - wrm)驱动器的转子磁场定向控制(RFOC)操作,以改善其动态性能。它提出了一种简单的、较少依赖参数的直流控制(DCC),直接使用来自定子侧的3l磁滞比较器和来自di - wrm驱动器转子侧的V/f型控制,对定子电流的定向dq分量进行控制。利用虚电压矢量的概念改进了定子侧的磁滞控制。定子侧磁滞控制器严密控制电机内产生的电磁转矩,V/f型控制器调节转子磁链和频率。通过对3KW di - wrm驱动装置的仿真和结果验证了所提出的控制算法。
This paper explores the rotor field-oriented control (RFOC) operation of the Double-Inverter-fed Wound Rotor Induction Machine (DI-WRIM) drive to improve its dynamic performance. It proposes a simple, less parameter-dependent, Direct Current Control (DCC) on the rotor-flux oriented $dq$-components of stator currents directly using 3L-hysteresis comparators from the stator side and V/f-type control from the rotor side of the DI-WRIM drive. The hysteresis control on the stator side has been improved using the virtual voltage vector concept. The hysteresis controller on the stator side tightly controls the electromagnetic torque developed in the machine, and the V/f type controller regulates rotor flux and frequency. The proposed control algorithm is validated with simulation and results for a 3KW DI-WRIM drive setup.
