A μ-synthesis robust controller of a four-wheel steering (4WS) vehicle is designed with the optimized weighting functions to attenuate the external disturbances while the yaw rate is chosen as the only feedback signal. Numerical simulation shows that the 4WS vehicle equipped with the μ-synthesis robust controller has better maneuverability and a stronger ability to resist disturbances; it is not sensitive to the variations in vehicle parameters. The μ-synthesis controller has an advantage over the H∞ controller; the latter is thought to be relatively conservative for normal ambient disturbances. © 2007 IEEE.
