摘　　要：针对双电源电动汽车的能量管理与驱动控制问题,对于隔离直流(DC)母线构型双逆变器开绕组永磁同步电机(PMSM)驱动系统进行定子电流优化及功率分配研究,并着重探究了动力电池与超级电容搭配下的功率分配策略。首先,建立双逆变器开绕组永磁同步电机驱动系统数学模型,并推导双空间矢量脉宽调制(SVPWM)架构下的双逆变器功率分配范围边界;然后,分别针对电机效率与功率分配范围提出两种定子电流矢量优化方法,并对比其稳态性能参数;最后,针对动力电池与超级电容的功率输出特性进行分析,在整车能量管理层面提出一种基于以上构型的双电源功率分配策略。使用仿真软件分别在城市道路以及市郊工况下,对所提功率分配策略进行验证。仿真结果表明,所提功率分配策略在节能性和稳定性方面具有优势。Targeting energy management and drive control of dual-power electric vehicles,stator current optimization and power allocation were investigated for an open-winding permanent magnet synchronous motor(PMSM)fed by a dual-inverter with an isolated direct-current(DC)bus configuration.The power allocation strategy for the hybrid system combining a power battery and ultracapacitor was specifically analyzed.First,a mathematical model of the dual-inverter open-winding PMSM was established,and the power allocation range under a dual space vector pulse-width-modulation(SVPWM)scheme was derived.Then,two stator current vector optimization algorithms were proposed to enhance motor efficiency and expand the power allocation range,respectively,with their steady-state performances compared.Finally,after analyzing the power output characteristics of power batteries and ultracapacitors,a configuration-based power allocation strategy was proposed for vehicle energy management.The proposed strategy was validated through simulations under urban and suburban driving conditions.Results demonstrate that the power allocation strategy achieves superior energy efficiency and operational stability compared to conventional methods.
