The human sensitivity to vertical acceleration at various frequencies is incorporated in the design of active suspension by using the linear quadratic regulator control method (LQR) with a frequency shaped cost functional. With this method, a decrease in vertical acceleration of the sprung mass is achieved over the range if frequencies which causes maximum discomfort to the human passenger. An invariant point which exist in the frequency response of the vertical acceleration of the sprung mass is removed by modifying the suspension system. Finally, the use of LQR method with frequency shaping has resulted in great improvement in the performance of the modified active suspension system.
