Controller Design of the Vehicle Active Suspension Based on Characteristic Structure Configuration

基于特征结构配置参数化方法，提出了车辆主动悬架控制器设计方法，其目的是设计一组状态反馈控制器，使得闭环结构系统具有希望极点和特征向量。该方法提供的自由参数，可用来满足系统的鲁棒性能等指标。该方法直接基于车辆悬架系统的参数矩阵，故便于工程应用。对车辆悬架系统进行仿真分析，结果表明该设计方法简单有效。

Based on the parametric method of characteristic structure configuration, a design method ot controllers in vehicle active suspension systems is proposed. It aims at designing a group of state-feedback controllers so that the closed-loop system will have the desired extreme point and its corresponding eigenvectors. The free parameters offered by this method can be selected to satisfy some system performance, such as robustness. The proposed method is involved directly in the data matrix and is convenient to use. A simulation analysis of a vehicle suspension system shows the simplicity and effectiveness of the proposed parametric design method.
