Abstract
In order to improve running speed at the curving section, tilting control systems have been developed. As the tilting control system, there are the pendulum type and air spring type. In the research field of the tilting control using air springs, there are very few researches of simultaneous control between tilting and vibration. In this research, simultaneous control between tilting and vibration using air springs are aimed. For the simultaneous control, the linear quadratic integral control theory was used.
