In the control system of permanent magnet synchronous motor, in order to improve real‐time performance and computational complexity, a new method of implementing segmented current control of permanent magnet motor using duty cycle modulation is proposed. The term plane is divided into three sectors through three‐phase voltage vector, and current prediction iteration is performed to obtain the relevant duty cycle, and the periodic modulation of this method (DM‐MPCC) is verified by experiments and the traditional DV‐MPCC (DV‐MPCC), the method is repeated more than 150 times, the time required for this method is 2.863 s, saving 52.073% of the computing time, while the modulation duty of DM‐MPCC It is also more stable than the waveform, and the current THD = 2.986% DM‐MPCC is much lower than the conventional method. DM‐MPCC has less pulsation on the dq axis at full speed than DV‐MPCC. The results show that the method has a faster operation speed and better real‐time performance, which shows the superiority of this method in practical applications.

This paper proposes pulse width modulation (PWM) methods for low inductance brushless DC (BLDC)motor drives that minimize the commutation torque ripples. An uneven current of non-commutation phase generates the commutation torque ripples. In the low inductance BLDC motor drives, two types of time delays in PWM also induce critical torque ripples. In this paper, the analyses of the time delays in PWM and their effects are introduced. Then, two PWM methods are proposed to eliminate the time delays in the commutation region and the conduction region, respectively. The commutation period is controlled to be synchronized to the switching period. In addition, the proposed methods synchronize the switching period to the commutation interrupt. As a result, the proposed methods effectively maintain the minimum commutation period as well as minimize the commutation torque ripples in the low inductance BLDC motor drives. The validity of the proposed methods is demonstrated by the simulation and experimental results in various driving conditions. The results show that the commutation period is remarkably shortened and the commutation torque ripples are reduced by 27.6% in comparison to the conventional method.
