Abstract: A control system and method for the seat suspension described herein utilizes a pneumatic cylinder which forms the shock absorber, an air compressor, solenoid valve and a microelectromechanical system (MEMS) based control. In operation, the pneumatic cylinder is filled with a compressible gas and sustained under pressure for the purpose of supporting the static weight of the occupant as well as providing comfort by reducing transmitted vibrations and high acceleration from external disturbances. A control process utilizes vibration data from the MEMS to adjust the gas cylinder pressure accordingly to reduce and damp the undulations of the supported mass.
