Semiactive Vibration Control of a Smart Seat with an MR Fluid Damper Considering its Time Delay

Abstract

The Lyapunov type robust control is applied to the semiactive vibration control of a controllable seat system to accommodate the modelling uncertainty of system and time delay of the damper. The seat system has a flexible mechanism of a spring and MR fluid damper between a seat cushion and base. Simulation results show that the robust control considering the time delay of the damper suppresses the seat vibration effectively.
