...Junghsen Lieh, Professor This paper studies the tire damping effect on the ride performance of a vehicle equipped with active suspension. Instead of first-order equation, a second-order approach is used for controller design. Both full-state and velocity-feedback concepts are considered...

...Mingsian R. Bai; Jienwen Lai A controller composed of a nonrecursive filter and a recursive filter is used to approximate the ideal controller for a spatially feedforward duct ANC problem. The nonrecursive part represents the dynamics of the transducer, whereas the recursive part is in the form...

...Gyo¨rgy Sza´sz and; George T. Flowers For a tuned or symmetrically mistuned bladed disk assembly, several vibration modes are coupled only to the axial dynamics, which forces controllers to rely on an axial actuator. A control strategy based upon deliberately mistuning in a nonsymmetric manner...

... disturbances. Feedback control via a collocated force actuator/rate sensor is introduced and recent advances in robust control theory are used develop controllers which achieve robust stability and performance with respect to the time-varying model. [S0739-3717(00)01101-6] Lehmann and Hutton 7 have...
