This paper describes the development of a damping control system for semi-active suspension which is based on nonlinear Hinfinite control theory instead of conventional linear control theory. A two degrees of freedom system is used as the structure for the vehicle suspension model. Since the structure is bilinear, it's not quite easy to design the controller. The authors designed the controller based on the Hamilton-Jacobi inequality by solving a linear Riccati equation. The authors were able to verify by simulation that nonlinear Hinfinite control theory made it possible to control vehicle vibration optimally and smoothly.
