| 英文摘要 |
| This paper suggests an H2 /generalized H2 output feedback control approach for active suspension control. Frequency-dependent weights of heave and pitch accelerations are determined according to ISO2631.3. In terms of the ground disturbance power spectral density, the H2 norm is used to describe the requirement for ride comfort and the generalized H2 norm is adapted to capture time-domain constraints such as good road holding. In the multi-objective control framework, the feedback controller can be designed by solving an LMI optimization problem. Based on a half-car model, analysis and simulation results of the designed output feedback active suspension are presented. |
