Abstract

To address vehicle drivetrain vibrations that cause discomfort and poor drivability, this study proposes a new active damping strategy with simple backlash compensation based on the simultaneous perturbation stochastic approximation (SPSA) with norm-limited update vector. First, an experimental device developed for a simplified drivetrain mechanism is demonstrated. A mechanism for reproducing both the contact mode and the backlash mode is included in the device. For the contact mode, a model-based [Formula: see text] controller is employed as the baseline damping strategy. Further, to mitigate the backlash effect, a simple algorithm based on mode-switching-based compensation is used with the [Formula: see text] controller. In particular, for the critical controller parameters, this article presents a systematic design approach to search for their optimal values. The key parameters, which are needed for the backlash and contact mode controllers, are simultaneously auto-tuned using norm-limited update vector-based SPSA, which ensures the stability in the iterative tuning. The novelty of this study is that both the backlash mode controller and the contact mode controller are simultaneously optimized by the improved version of SPSA, thus realizing a comprehensive auto-tuning design of an active drivetrain damping system. Finally, the active controller is experimentally verified using the actual test device. Comparative studies show that the proposed approach significantly reduces drivetrain vibrations and is robust against fluctuations in the backlash.
基于规范限制 SPSA 的具有反向间隙非线性的车辆传动系统主动振荡控制器的实验验证
汽车动力传动系统的振动会给驾驶者带来不适感并降低驾驶性能,为解决这一问题,本研究基于同步扰动随机近似(SPSA)和规范限制更新向量,提出了一种具有简单反向间隙补偿的新型主动阻尼策略。首先,演示了为简化传动系统机构开发的实验装置。该装置中包含一个可重现接触模式和反向间隙模式的机制。对于接触模式,采用基于模型的[公式:见正文]控制器作为基准阻尼策略。此外,为减轻反向间隙效应,[公式:见正文] 控制器采用了基于模式切换补偿的简单算法。特别是对于关键的控制器参数,本文提出了一种系统的设计方法来寻找其最佳值。反向间隙和接触模式控制器所需的关键参数同时采用基于规范限制更新矢量的 SPSA 进行自动调整,从而确保了迭代调整的稳定性。本研究的新颖之处在于通过改进版 SPSA 同时优化了反冲模式控制器和接触模式控制器,从而实现了主动传动系减震系统的全面自动调谐设计。最后,利用实际测试设备对主动控制器进行了实验验证。对比研究表明,所提出的方法能显著降低传动系统的振动,并对反向间隙的波动具有鲁棒性。
