摘要
研究双电机硬联结负载功率平衡问题,在双电机硬联结负载系统中,由于两台相同电机参数略有差异,将导致功率分配不平衡。根据矢量控制原理,使用主从控制和交叉耦合概念设计的系统基本上解决了功率不平衡问题,但其功率平衡精度和动态性能不佳。为了提高功率平衡精度和改善动态性能,又加入"差矩反馈"环节。仿真结果表明,加入"差矩反馈"的系统与只含主从控制和交叉耦合的系统相比,可以提高功率跟踪的动态性能和功率平衡性精度。
The parameter differences between two same motors rigidly - connected in a driving system, will lead to a power variation. According to the principle of vector control, the system was designed by using master - slave control and cross coupling concept, which can balance the power. Then we joined the ＂Torque Differences feedback＂ link to improve the power balance accuracy and dynamic performance. The simulation results with MATLAB indicate that compared with the system that only includes the master - slave control and cross coupling, the system joined ＂Torque Differences feedback＂ link has obvious advantage on the tracking and balance of power.
