| Abstract | |
Brushless DC (BLDC) motor is used in a wide range of applications due to its high efficiency and high power density. However, as its main drawback, it develops significant torque ripple during phase commutation in conventional 120 degrees conducting mode operation. To reduce torque undulations, this paper presents a simple approach for BLDC motor drive by applying a model-based predictive direct power control (MPDPC) with duty cycle concept. As a result of controlling active and reactive power exchanged between stator and rotor, low torque ripple can be achieved. Compared to priors works, this paper introduces the duty cycle concept with lower complexity and number of calculations to improve the conventional MPDPC steady-state performance. The effectiveness of proposed approach is demonstrated by simulation results. (AU) | |
