摘要
电控空气悬架可以方便地实现主动或者半主动控制策略,其应用的效果要好于被动空气悬架系统。分析了基于参考模型自适应的电控空气悬架的控制策略分析,将控制策略分为两部分,离线部分和在线部分。通过离线工作利用LQG算法,求得特定工作点的参考模型,在线部分估计出工作点,同时利用参考模型自适应算法,使整个悬架控制系统接近参考模型。
The electronically controlled air suspension can easily realize active or semi-active control strategy and its effect is better than the passive air suspension system. In this article, an analysis on the control strategy is made based on model reference adaptive electronically controlled air suspension, dividing the control strategy into two parts： offline part and online part. A model reference at a specific operating point can be obtained by LQG algorithm through offline operation. The online part estimates the operating point while making the whole suspension control system close to the model reference by using the model reference adaptive algorithm.
