The invention relates to an active suspension control method based on depth determinacy strategy gradient, and belongs to the technical field of automobile dynamic control and artificial intelligence.The implementation of active suspension control is divided into three stages, firstly, a simulation training process is carried out, a suspension control strategy is expressed by a neural network, and parameters of the control strategy are updated by adopting a depth deterministic strategy gradient algorithm; secondly, a trained strategy is downloaded, and after training convergence, parameters and the structure of the neural network are stored as a trained control strategy; and finally, the trained strategy can be directly applied on line, and active suspension vibration reduction control isachieved. The active suspension control method based on the depth determinacy strategy gradient is adopted, the neural network is fully trained on a large number of random road surfaces, the obtainedsuspension control strategy has great generalization performance, an active suspension system can effectively play a role in vibration reduction under the condition of variable road surfaces, and therefore riding comfort is guaranteed, and meanwhile the overall safety of a vehicle is guaranteed.

    本发明涉及一种基于深度确定性策略梯度的主动悬架控制方法,属于汽车动态控制和人工智能技术领域。本发明中主动悬架控制的实现分为三个阶段,首先为仿真训练过程,用神经网络表示悬架控制策略,采用深度确定性策略梯度算法更新控制策略的参数。其次下载训练好的策略,当训练收敛后,神经网络的参数和结构被保存为训练好的控制策略。最后,训练好的策略可直接进行在线应用,实现主动悬架减振控制。采用基于深度确定性策略梯度的主动悬架控制方法,在大量随机路面下充分训练神经网络,得到的悬架控制策略巨有泛化性能,使主动悬架系统能在多变的路面情况下有效发挥减振性能,从而确保乘坐舒适性,同时保证车辆整体的安全性。
