摘要

The traditional control method of nine-phase induction motor suffers from increased computational burden and limited flexibility. Aiming to tackle such a problem, a modular model predictive current control strategy for nine-phase induction motors is proposed in this paper. By mathematical transformation method, the nine-phase motor system is decoupled into three independently controlled three-phase motor units. The algorithm can adjust the output power of three sets of windings independently while maintaining the steady-state accuracy and dynamic response characteristics of the system. This characteristic of the proposed strategy enables the motor to selectively reduce the output power of certain windings under abnormal working conditions and to optimize the stator copper loss under the condition of unbalance of resistance of three sets of windings. This research has important engineering application value for improving the operational reliability, flexibility and energy efficiency of nine-phase induction motor system.
