汽车主动悬架的自适应控制研究

主要对汽车主动悬架自适应系统进行研究。根据悬架系统的模型,参数往往不确定,路面激励未知且可变,对主动悬架的非线性性能特点进行研究。采用增益调度控制、模型参考自适应控制和自校正控制等几类自适应控制策略应用于主动悬架的主动控制系统。通过自校正控制自适应系统,按照路面行驶工况进行最优控制,通过计算机对电液系统的阻尼、弹力和水平位置等进行调节,使悬架系统对不同运行工况具有最大程度的适应能力。确保主动悬架性能满足车辆行驶稳定性能与乘坐舒适性,实现对悬架的自我优化控制。

Research on Adaptive Control of Vehicle Active Suspension

The main research of vehicle active suspension adaptive system. According to the model of the suspension parameters are often uncertain, road excitation is unknown and variable, to study the nonlinear characteristics of active suspension. The gain scheduling control, model reference adaptive control and self-tuning control and other types of adaptive control strategy for active suspension control. Through the use of self-tuning adaptive control system, according to the road conditions are optimal control, through the computer to the electro-hydraulic system damping, elastic and horizontal position adjusted, so that the suspension system has the greatest degree of adaptation to different operating conditions. Ensure that the suspension performance to ensure that the vehicle performance and comfort, to realize the optimal control of suspension.
