Look-ahead Preview Control with Limited Bandwidth Active Suspension - Application to Tracked Vehicle Systems

제한 대역폭을 가진 능동 현가 장치에 대한 Look-ahead 예견 제어-궤도 차량에의 응용

The look-ahead preview control with the use of limited bandwidth active suspensions is presented. Both a linearized racked vehicle model and a complex nonlinear model based on a commercial multibody dynamic program are used to verify the performance of preview control. The performance of the preview control system is evaluated on the ride quality which is estimated from the acceleration of the driver position. Due to the practical advantages associated with the use of limited bandwidth active control in comparison with full bandwidth systems, the results are considered important to the future development of active tracked vehicle suspensions.
