电控空气悬架系统阻尼多模式自适应切换控制研究

提出了一种阻尼多模式自适应切换控制思想，根据车辆实际行驶工况和电控空气悬架性能特点，分别设计了车身高位、车身中位、车身低位以及转向工况4种阻尼控制模式，并采用逻辑判断方法制定了各模式间的切换策略，通过Simulink/Stateflow建立了多模式自适应切换控制系统，使得系统能够根据实际工况选择最佳的阻尼控制模式。在此基础上，基于不同模式所侧重的控制目标，分别设计了相应的阻尼力局部控制器，从而保证了系统的局部控制性能。最后进行了控制系统的实车道路试验，验证所提出的电控空气悬架系统阻尼多模式自适应切换控制方法的有效性和实用性。

Damping Multi-mode Adaptive Switching Control of ECAS System

A damping multi-mode adaptive switching control mode was proposed. According to the actual vehicle driving condition and the performance characteristics of electronically controlled air suspension (ECAS), four damping control modes, such as high body height mode, middle body height mode, low body height mode and steering mode, were designed. The switching strategy between different modes was made by logical judgment. By using Simulink/Stateflow, the multi-mode adaptive switching control system was established, which could choose the optimum damping control mode according to the actual driving condition. Based on the control objectives of different control modes, the corresponding damping local controllers were designed to guarantee the local control quality of the system. The vehicle tests of the control system were carried out finally, and the effectiveness and availability of the control method proposed was verified by the experimental results.
