摘要：

The traditional vector control system cannot achieve good dynamic and steady-state performances because it cannot match the model of dual three-phase induction motor due to its multi-winding structure. Besides, the d-q currents of system are coupled and unbalanced in synchronous rotating coordinate frame. The traditional PI control method with compensated voltage is sensitive to parameters and its decoupling capability is limited. Thus, the torque response speed will be affected. Regarding to the series of questions, a vector control system for dual three-phase induction motor based on a superposition of complex regulators was proposed. The complex vector model of dual three-phase induction motor was established. The coupling voltages were simplified into system with flux indicated by complex current, and the d-q currents were decoupled completely. Meanwhile, a superposition in fundamental and error planes had been used in the current link control method and a superposition of complex regulators had been designed, which could reduce the system dependence on parameters and balance the currents of the two windings. The simulation and experimental results have verified the correctness and feasibility of the proposed method. © 2015 Chin. Soc. for Elec. Eng.
