Robust active damping design for a suspension system

Abstract EN

This paper proposes a control of robust active damping for a quarter car model with three degrees of freedom by using an optimal control approach.

The design takes into consideration the uncertainty of system parameters.

The solution to the robust damping problem is obtained by translating it into an optimal control problem, and the subsequent design of appropriate feedback controllers for the active suspension system can be obtained by solving the LQR (linear quadratic regulator) problem.

The results show that the proposed robust design provides superior kinematic and dynamic performance compared to those of the passive system.
