摘要:

本文研究应用于电子机械制动(EMB)系统的无刷直流电机(BLDC)低成本正弦波驱动控制策略。针对低成本方案所面临电机冷启动困难、转子位置估算精度低、相位超前角设置不合理导致电机效率低,以及电机转速计算和控制精度低等技术难点,提出了基于电机负载观测器的正弦波冷启动方法、基于ARIMA模型的转子位置估算方法、基于遗传算法的相位超前角自调节方法、基于霍尔区间的转速计算方法以及基于模型预测控制(MPC)的转速控制方法。最后进行台架试验,证明所提控制策略可以显著提高电机效率,扩大高效运行区间,并在不增加硬件成本的前提下优化电机性能,推动了EMB系统的工程应用。

Abstract:

In this paper, a low-cost sinusoidal drive control strategy for brushless DC (BLDC) motor applied to electro-mechanical brake (EMB) is studied. For the technical challenges associated with low-cost solutions, including difficulties with motor cold starting, low accuracy in rotor position estimation, and inefficient motor operation due to suboptimal phase advance angle settings, as well as low precision in motor speed calculation and control, a sinusoidal cold-start method based on motor load observers, a rotor position estimation method using low-resolution switch hall sensors, a self-adjusting phase advance angle control method based on genetic algorithms, a low-cost speed calculation method, and a speed control method based on model predictive control are proposed. The bench tests results show that the proposed control strategy effectively improves motor efficiency, expands the high-efficiency operating range, and optimizes motor performance without increasing hardware cost, thereby promoting the engineering application of EMB.
