Research On Ultra-high Speed Cigarette Making Machine Drums System Electromechanical Co-simulation

Drums system is the important functional unit of cigarette making machine thatdeveloping to high speed, high efficiency and low consumption. Drums system withmechanical drive can’t meet the requirements of cigarette making. Instead ofmechanical drive, independent servo drive technologies become the key point ofcigarette making machine. With the developing of independent servo drive, thedividing line between mechanical system and control system becomes blurred. Directdrive technologies provide new ideas to mechanical design. Based onADAMS/MATLAB co-simulation, electromechanical system was analyzed. And akind of Electromechanical co-simulation analysis method of independent servo drivemulti-axis synchronous control system was presented. The accuracy of the simulationmethod was verified that combined to experiment.Based on the analysis of current situation of co-simulation study, keytechnologies of multi-axis drums system co-simulation was analyzed. Targeted atdrums system of cigeratte making machine, the load of drums was analysed in detailfirst. The multi-axis drums system’s dynamic model was built and the dynamicbehavior of exemplary drums was analysed. Second, based on analyzed of controlsystem, the PMSM model and three loops control model which contains current loop,velocity loop and displacement loop were built. Detailed parameters of the debuggingprocess were presented too. The multi-axis drums dynamic model and co-simulationmodel were built through the software interface. Then, synchronization errors invirtual axes structure system were analysed on the model. The influence of feedforward and coupling were analysed too. The results show that multi-axis drumssystem’s synchronization precision is high and meet the design requirement well. Thefeed forward and coupling can improve system’s synchronization performance.Finally, the experimental system was built. System’s synchronizationperformance was verified and the torque from experimental system was comparedwith dynamic characteristics. The experimental results show that synchronizationerrors and follow errors of multi-axis drums system with the virtual axis master-slavestructure were in allowed range and meet the design requirement well.
