In recent years, the development of multi-three-phase drives for both energy production and transportation electrification has gained growing attention. An essential feature of the multi-three-phase drives is their modularity since they can be configured as three-phase units operating in parallel and with a modular control scheme. The so-called multi-stator modeling approach represents a suitable solution for the implementation of modular control strategies able to deal with several three-phase units. Nevertheless, the use of the multi-stator approach leads to relevant coupling terms in the resulting set of equations. To solve this issue, a new decoupling transformation for the decoupled torque control of multi-three-phase induction motor drives is proposed. The experimental validation has been carried out with a modular power converter feeding a 12-phase induction machine prototype (10 kW, 6000 r/min) using a quadruple three-phase stator winding configuration.

多三相异步电动机驱动器的解耦和模块化转矩控制

近年来，用于能源生产和交通电气化的多相三相驱动的开发越来越受到关注。多三相驱动器的一个基本特征是它们的模块化，因为它们可以配置为并联运行的三相单元并采用模块化控制方案。所谓的多定子建模方法代表了一种适用于实施能够处理多个三相单元的模块化控制策略的解决方案。然而，多定子方法的使用导致结果方程组中的相关耦合项。为了解决这个问题，提出了一种用于多三相异步电动机驱动器的解耦转矩控制的新解耦变换。
