Study on Optimum-Preview Control of Vertical Active Suspension of Rail Vehicle |
| |
Abstract: | A vertical dynamics model of 6 degrees of freedom for a passenger rail vehicle of four axles was built in this paper. Meanwhile an optimum-preview controller was designed to restrain the vertical vibration of rail vehicle system. The results of the research indicate that the vertical vibration of rail vehicle system can be restrained effectively and the speed of response can be greatly improved by using optimum-preview strategy. |
