Title:
DAMPING FORCE CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2010/073412
Kind Code:
A1
Abstract:
A state feedback controller (K) of a generalized plant (G) is so designed that the L2 gain of a closed loop control system (S) including the generalized plant (G) designed by using a lag approximation model (M) and the state feedback controller (K) is below a predetermined positive constant γ. According to a control input u calculated by the state feedback controller (K), the damping force generated by a damping force generator is controlled by operating an actuator. The lag approximation model (M) is designed so as to be approximated to a bilinear system, i.e., a lag consideration model which is a control model made from the mechanical motion model of the damping force generator in consideration of the lag of the operation of the actuator by causing a lag element R indicating the lag and a lag compensation element R* cancelling the lag to act on the mechanical motion model of the damping force generator.
