...J. C. Collinger; J. A. Wickert; L. R. Corr An autonomous vibration controller that adapts to variations in a system’s mass, stiffness, and excitation, and that maximizes dissipation through synchronized switching is described. In the model and laboratory measurements, a cantilever beam is driven...

... of each one. Then, a higher-order level supervision algorithm decides in real time the estimator that will parametrize the adaptive controller at each time instant according to the values of the above supervisory indexes. There exists a minimum residence time between switches in such a way that the closed...

...Shahin S. Nudehi; Ranjan Mukherjee, Assoc. Professor Many dynamical systems use transducers that can function both as actuators and sensors. It is possible to continuously switch the functionality of the transducer elements in such systems and effectively use each element both as an actuator...

..., specifically by minimizing the excursions of pressures experimented in the system and by minimizing the time required by the supply pump to restore pressure. The design stores fluid energy and restores it to a system where fast switching devices control fluid consumption. The effectiveness of the mechanism...
