Description

The purpose of this study was to examine the effectiveness of active seat suspension when it is applied to small cars, and to survey the problems associated with its practical use. A small active seat suspension, which is easy to install, was designed and manufactured for one-seat electric automobiles. In a realistic driving test, a test road was prepared in which the concavity and convexity of an actual road surface were simulated by using hard rubber. Our aim was to examine the vibration isolation effect for the driver's seat, using disturbance cancellation control. We examined the control performance with respect to the variation of the parameters for the frequency and the driver's weight. We performed experiments in several conditions, and compared the results of control performance with passive control, feedback control, feedforward control, and disturbance cancellation control. As a result, we confirmed the suppressive effect of the disturbance cancellation control.
