摘 要: | 为改善汽车的行驶平顺性和操纵稳定性,采用七自由度整车模型,设计主动悬架H2/广义H2多目标输出反馈控制器。为解决控制器阶数过高的问题,在此基础上采用Hankel范数最优降阶法对全阶控制器进行降阶研究。然后将降阶控制器应用于主动悬架系统,结果表明,设计的降阶控制器在保证操纵稳定性的同时可大大提高行驶平顺性。 |

Abstract: | To improve the riding comfort and handling stability performance of vehicle, a multi-objective and mixed H2/generalized H2 output controller is devised for an active suspension system by using seven degree-of-freedom full-car model. Then the optimal Hankel-norm reduction method is utilized for the designed high-order controller. The simulation results demonstrate that the reduced-order controller obtains a better performance of riding comfort while guaranteeing handling stability performance. |
