摘要

本文给出了15相无刷直流电动机的变换矩阵和数学模型。该数学模型可用于无刷直流电动机的磁场定向控制。根据该模型，提出了一种容错控制系统，以保证15相无刷直流电机在定子断相失路情况下的高性能。仿真结果表明，该容错系统能够满足定子绕组发生开路故障时的无扰动运行要求。

The mathematical model and field-oriented control for 15-phase brushless direct current motor with an opened phase

The paper presents a transformation matrix and a mathematical model for 15-phase brushless direct current (BLDC) motor with an opened phase. With the mathematical model, the field-oriented control can be put into use for the BLDC motor. According to the model, a fault-tolerant control system is proposed to guarantee the high-performance of 15-phase BLDC motor subject to the loss of one of a stator phase opened circuit. Simulation result reveals that the fault-tolerant system can meet the demand of disturbance-free operation when the open-circuit fault occurs in stator windings.
