Abstract
The present invention provides a suspension control apparatus capable of an excellent vibration control by a model thereof designed to incorporate nonlinearity and a time-lag element of a control damper. The present invention employs the backstepping method which is one of nonlinear control methods, and is designed so as to incorporate the nonlinearity of a damper 4. In addition, a nonlinear controller 5 uses a damping force Fu obtained by expressing the dynamics of a damping force characteristic variable portion [damping force Fu(v, i)] by a first-order lag system, so as to compensate the dynamics of the damper 4, whereby a control system is formed so as to incorporate the time-lag element of the control damper. As a result, it is possible to reduce time lag, and to practically adjust a control force according to the characteristics of the control damper.
