International Journal of Vehicle Design (IJVD), Vol. 36, No. 4, 2004

Abstract: In this article, the human sensitivity to vibration acceleration at various frequencies is incorporated in the design of active suspension by using the frequency-shaped linear-quadratic-Gaussian (LQG) method. And three new sufficient conditions of stability robustness for the frequency-shaped LQG active suspension systems subject to both disturbance/noise uncertainties and linear time-varying parameter perturbations are also presented in this article. The proposed new sufficient conditions provide a quantitative measure for automotive designers to design the frequency-shaped LQG active suspension systems with robustness properties. An illustrated example is given to demonstrate the applicability of the proposed new sufficient criteria.
