对于串并联型混合动力汽车(HEV)来说，由于离合器在模式转换过程中的接合，驾驶性能问题是一个重要且难以解决的问题。本文针对串并联型混合动力汽车设计了一种鲁棒控制器，以减小模式转换过程中车辆的抖动，提高车辆的行驶性能。首先，得到被控对象的线性动态系统模型，用于鲁棒控制设计。然后，基于MU综合法设计了鲁棒控制器，并采用离散D-K迭代法进行求解，在设计过程中考虑了系统模型中的参数不确定性，以保证控制系统的鲁棒性。最后，通过半实物仿真对所提出的控制器进行了验证。半实物仿真平台由测功机模拟发动机、真实变速器、虚拟电机和基于轮胎、路面和车身非线性动力学构建的虚拟车辆组成。半实物仿真结果表明了所提出的鲁棒模式转换控制的有效性。
For series-parallel hybrid electric vehicles (HEVs), problems of driveability are significant and difficult to solve due to clutch engagement during mode transitions. In this paper, a robust controller was designed for a series-parallel HEV to reduce vehicle jerk during mode transitions and improve vehicle driveability. First, a linear dynamic system model of the controlled plant was obtained for robust control design. Then, the robust controller was designed based on the mu-synthesis method and solved using the discrete D-K iteration; parameter uncertainties in the system model were considered in the design process to ensure the robustness of the control system. Finally, a hardware-in-the-loop (HIL) simulation was performed to verify the proposed controller. The HIL platform was composed of a dynamometer-simulated engine, a real transmission, a virtual electric machine, and a virtual vehicle, which was constructed based on the nonlinear dynamics of tires, road, and vehicle body. The HIL simulation results showed the effectiveness of the proposed robust mode transition control.
