论文编号18 -00430 © 2019日本机械学会[DOI：10. 1299/jamdsm.2019jamdsm0018]摘要为了在发动机特性所导致的控制周期限制下，维持稳定性和控制性能，提出了一种带齿隙的汽车驱动系统的振动控制方法。在改善汽车的乘坐舒适性和驾驶性能时，减少汽车驱动系统的振动仍然是一个挑战。特别是，必须开发一种振动控制方法来补偿差动齿轮的齿隙，因为该元件降低了振动控制性能。此外，用作致动器的发动机由于输入更新的限制而具有使控制周期更长的约束。粗略更新的周期不仅对高振动控制性能而且对稳定性产生不利影响。在这项研究中，我们通过考虑输入更新限制来验证具有间隙的汽车驱动系统的控制系统。首先，一个基本的实验装置，它抽象的实际车辆集中在由于反冲的影响，而只反映了汽车驱动系统的基本结构，创建。然后，以科普控制周期的约束，采样数据H2控制应用。伺服系统的构成，通过应用一个近似积分器和频率成形。作为补偿齿隙的一种方法，我们提出了一种简单实用的控制模式切换技术。最后通过实验验证了控制系统的有效性。将所得结果与传统离散近似控制结果进行了比较。
Paper No.18-00430 © 2019 The Japan Society of Mechanical Engineers [DOI: 10.1299/jamdsm.2019jamdsm0018] Abstract This paper proposes a vibration control method of an automotive drive system with backlash to maintain stability and control performance under the control period constraint due to an engine’s characteristics. Reducing the vibrations of the automotive drive system remains a challenge when improving the riding comfort and driving performance of automobiles. In particular, a vibration control method must be developed to compensate for the backlash of differential gears because this element degrades the vibration control performance. Furthermore, engines used as actuators have a constraint in which control cycles are made longer due to restrictions of the input update. The roughly updated cycles adversely affect not only the high vibration control performance but also the stability. In this study, we validate the control system for an automotive drive system with backlash by considering the input update limitation. First, a basic experimental device, which abstracts actual vehicles to focus on the influence due to backlash while reflecting only the basic structure of an automotive drive system, is created. Then to cope with the control cycle constraint, sampled-data H2 control is applied. The servo system is constructed by applying an approximate integrator and frequency shaping. As an approach to compensate for backlash, we propose a simple and practical control mode switching technique. Finally, the effectiveness of the control system is verified experimentally. The results are compared to the control results with those obtained by the traditional discrete approximation.
