【摘要】：双三相感应电机控制系统因其固有多绕组结构,使传统矢量控制方案无法契合电机模型实现良好动稳态性能,导致系统在同步旋转坐标系下d-q轴电流存在耦合,且常伴随电流不平衡。传统PI及电压补偿方案解耦能力有限且对参数敏感,影响系统转矩响应速度。针对此系列问题,该文提出一种基于叠加复调节器的双三相感应电机矢量控制方案,通过建立双三相感应电机的复矢量模型,采用复矢量电流表示磁链将耦合电压直接化入系统,实现d-q轴电流完全解耦。电流控制环节采用基波平面电流与误差平面电流叠加控制,同步设计叠加复调节器,在减小系统对参数依赖性的同时实现了两套绕组电流平衡。仿真及实验结果均验证了所提方法的正确性与可行性。
[Abstract]:Because of its inherent multi-winding structure, the traditional vector control scheme can not accord with the motor model to achieve good dynamic and steady performance, which leads to the coupling of d-q axis current in the synchronous rotating coordinate system. And often accompanied by current imbalance. The decoupling ability of traditional Pi and voltage compensation schemes is limited and sensitive to parameters, which affects the torque response speed of the system. Aiming at this series of problems, this paper presents a vector control scheme of double three phase induction motor based on superposition complex regulator. By establishing the complex vector model of double three phase induction motor, The coupling voltage is directly transformed into the system by using the complex vector current representation flux, and the d-q axis current is completely decoupled. In the current control link, the fundamental current and the error plane current are superimposed, and the superposition complex regulator is designed synchronously. The two sets of winding current balance are realized while reducing the dependence on the parameters of the system. Simulation and experimental results verify the correctness and feasibility of the proposed method.
