Abstract

This paper deals with the control system design of active seat suspension. The proposed control system structure is built basing on several various controllers. The primary controller is used to evaluate the actual value of the desired active force that should be generated in the suspension system. The secondary controller is employed to calculate the instantaneous value of a signal which controls the active element by means of its reverse model. The adaptation mechanism recognises the actual suspended mass in order to increase the effectiveness of vibration isolation. Additionally, the system robustness for different load masses is investigated using computer simulation and experimental research.
