采用虚拟电机的改进偏差耦合多电机同步控制
Multi-Motor Speed Synchronous Control Based on Improved Relative Coupling Structure With a Virtual Motor
摘要
Abstract
According to the large synchronization error in the starting period and the wide range of content in speed synchronous compensators of the traditional relative coupling control,this paper presented an improved relative coupling control structure for multi-motor speed synchronization.The proposed structure introduces the concept of the "virtual motor",making each motor follow the path of the virtual motor in the starting period and reducing the synchronization error effectively at the same time.The improved relative coupling structure makes each motor's speed feedback apply to the "virtual motor",thus there is no direct coupling effect among each motor.Synchronous control of each motor is carried by the "virtual motor",which can simplify the speed synchronous compensator.Compared with the traditional structure,the improved structure can also reduce the tracking error of each motor to a certain extent and meanwhile keep the same synchronization under the same load disturbance in the steady state.关键词
