摘　　要：基于交流传动互馈试验台,研究和实现了改进的转差频率控制策略。在该控制系统中,同时分别控制联轴驱动的交流电机和作为负载的交流电机,应用PI调节器实现了对互馈试验台速度和电流的双闭环控制,采用电压空间矢量脉宽调制(SVPWM)的控制算法。在互馈试验台上完成了功率100kW的系统试验,试验结果证明了这种控制策略的有效性。This paper studies and realizes the improved slip frequency control strategy based on reciprocal power-fed AC drive test rig.The PI controller was used,the double closed-loops including speed control and current control were realized,the SVPWM method was adopted,the driving induction motor and load induction motor with coupling-axes are simul controlled respectively in this system.The system experiment with the running power of 100kW is finished in this test rig, experimental results shows the feasibility of the control strategy.
