摘要

本文评估了模块化动力传动系统与基准动力传动系统相比的能耗、控制性能和特定应用功能要求。利用机械设备模型开发并验证了分散控制架构。Simscape 模型已通过实验装置(包括等效模块化和基准传动系统)的数据进行了验证。此外,还在实验装置上实施并验证了控制策略。结果证明,该控制策略能够同步不同滑块的运动,使曲柄位置跟踪误差低于 0.032 弧度。模型和实验数据表明,与基准动力传动系统相比,模块化动力传动系统在能耗、控制性能和功能要求方面的性能都有所提高。由于惯性减小,模块化动力传动系统对于运行高动态运动曲线的机器尤其有利。在这种运动情况下,测得的位置跟踪率最高可提高 84%。此外,与基准传动系统相比,模块化传动系统的均方根(RMS)扭矩降低了 32%。然而,模块化传动系统中较高的电机损耗部分抵消了这些机械能耗的节省,从而可能节省约 29% 的电能。

Increased Dynamic Drivetrain Performance by Implementing a Modular Design with Decentralized Control Architecture
This paper assesses the energy consumption, control performance, and application-specific functional requirements of a modular drivetrain in comparison to a benchmark drivetrain. A decentralised control architecture has been developed and validated using mechanical plant models. Simscape models have been validated with data from an experimental setup including an equivalent modular and benchmark drivetrain. In addition, the control strategy has been implemented and validated on the experimental setup. The results prove the ability of the control strategy to synchronize the motion of the different sliders, resulting in crank position tracking errors below 0.032 radians on the setup. The model and experimental data show an increased performance of the modular drivetrain compared to the benchmark drivetrain in terms of energy consumption, control performance, and functional requirements. The modular drivetrain is especially advantageous for machines running highly dynamic motion profiles due to the reduced inertia. For such motion profiles, an increased position tracking of up to 84% has been measured. In addition, it is shown that the modular drivetrain root mean square (RMS) torque is reduced with 32% compared to the benchmark drivetrain. However, these mechanical energy savings are partly counteracted by the higher motor losses seen in the modular drivetrain, resulting in potential electrical energy savings of around 29%.
