Optimal Control for Automobile Active Suspension Using Frequency-shaped Performance Index |
| |
| Abstract: | This Paper develops a Control law of active suspension for ride quality improvement. The performance is represented by frequency-shaped index according to the vibration characteristics of sitting, body. Introducing the frequency-dependent weighting matrices allow one to emphasize the specific variables related to the vibration at specific bands of frequencies. The numerical results show that active suspension greatly reduces the vertical acceleration of sprung mass and the vibration intensity in the range of frequencies sensitive. to sitting body can be further lowered by the used of frequency-dependent weighting function |
