| Abstract: | The vibration control question of the uncertainty parameter suspension system was studied.Using the multidimensional convex model theory,the vibration control problem of vehicle suspension system with uncertain parameters approximated by a deterministic one was discussed.Using the convex model theory,the uncertain parameters impact on the vehicle suspension systems was analyzed based on matrix perturbation method,and estimating the upper and lower bounds of the real and imaginary parts of eigen values of the closed-loop systems was presented.The calculation results of two freedom degrees vehicle suspension system show the effectiveness of the method. |
