Abstract
It is proposed to design a controller using the goal of emulating the dynamics of a sky-hook damper with a continuously modulated damper system. To minimize the damping force error between the modulated damper and the sky-hook damper, it was decided to use LQR control design. This type of control was performed by using an ER damper. (Yoshida, et al., 1997) In this research it is desired to examine the same type of control, but applied to a more general type of modulated damper. This damper has a variable orifice controlled by a stepping motor. In addition, in this research the plant model is a half-car model (vertical and pitch motions) of one front wheel and one rear wheel suspension. Therefore it is thought it may be possible to use some form of predictive control using information from the front tire to control the rear wheel suspension.
