Abstract: The stability of the linear optimal controlled vehicle
suspension system, which contains some nonlinear elements and
there is time delay in the control circuit is studied. The
stability interval of time delay is determined. The periodic
movement of the system is analyzed by Hopf bifurcation theorem
when time delay is at its critical point. The corresponding
simulating results are given.
Key words: Car Active suspension Time delay Hopf bifurcation
