汽车电动助力转向与主动悬架系统的集成控制

The electric assistance steering and the integrated control of the active suspension system

针对基于横向和垂向动理学的电动助力转向（EPS）与主动悬架（ASS）集成系统，设计了一种基于干扰抑制指标的控制策略。首先根据控制目标，选择相应的加权函数，建立增广被控对象矩阵，将鲁棒性能控制问题转化为标准的控制问题；然后在Matlab环境下进行了仿真计算。仿真结果表明，该集成控制方法是有效的，能够使汽车转向行驶时的整车综合性能得到提高。

According to the EPS AND ASS integrated system which based on the transversal and vertical dynamics, designing a control strategy based on interference control index. First according to the control target choosing related weighted function to set up enlarging controlled matrix change the LB function control to standard H∞ control. Then doing the emulation calculation under the MATLAB/Simulink environment. The results show that the method is effective it can make the improve the steering performance while driving.
