摘要
如何在独立轮转向架上进行左右车轮耦合以提高导向能力,并降低牵引损耗以便提升牵引效率,是100%低地板新型有轨电车的技术难点和研究热点…。建立一种考虑铁耗的内置式永磁同步电机最小损耗求解模型,并采用自适应模糊控制器解决多电机联合控制时的效率寻优问题。使用一种集成效率优化策略,在牵引系统启动阶段,采用最低损耗控制策略(lowest loss control,LLC)进行单电机效率优化控制;在牵引系统恒速稳定运行时,基于最小输入功率的模糊控制开始介入,对基于GPS速差前馈的多电机牵引系统进行整体效率优化。仿真结果表明,与传统的基于单电机MTPA控制相比,集成效率优化策略具有响应速度快、超调量小、鲁棒性好等优点,尤其是能明显降低永磁牵引系统电气损耗。
In the bogies with independent wheels applied in 100% low floor tram,how to improve steering ability and reduce the electrical loss of traction in order to enhance the efficiency of traction,is the technical difficulty and research focus. A minimum loss solution model of IPMSM base on iron loss was established,and used self-adapted fuzzy controller to solve the problem of multi motors efficiency optimization. An integrated efficiency optimization strategy was proposed in permanent traction system,in traction system acceleration process,used lowest loss control(LLC)strategy to optimize the efficiency of single motor;in traction system constant speed process,the fuzzy control strategy based on minimum entered power began to work,which optimized multi motors traction system based on the feedforward of speed difference of the parallel wheels from GPS. The simulation results show that,compared with the traditional MTPA control strategy of single motor,the integrated efficiency optimization strategy has the great response speed,the smaller overshoot,and the robust advantages,in particular,it can significantly reduce electrical loss in permanent magnet traction systems.
