【摘要】 本文设计了一种基于DSP的专用于短距离运输的微型电动车 (MicroEV)的永磁无刷轮毂电机控制系统 ,提出的控制策略是进行电压控制的同时进行对应于加速踏板踏位的电流预测控制 ;仅采用一个置于直流端的霍尔电流传感器实现了相电流的检测 ;软件设计中摈弃通常使用捕获单元的方式 ,仅采用一个通用定时器实现各项控制。实验表明 ,样机系统具有良好的性能 ,满足微型电动车驱动的要求。更多还原

【Abstract】 A novel permanent magnet in-wheel motor control system based on DSP for a micro EV is presented. A new control strategy is proposed, several novel aspects are discussed in detail, such as the detection of phase current by one current sensor, the software design with new technique etc.. Experimental results are shown that the designs are reasonable and good performance which is valuable for the engineering application of EV can be achieved.更多还原
