Acute Effects of Mechanical Vibration
1986
We know that man possesses a highly developed ability to adjust to different environmental conditions. For this function there are physiological regulatory systems, which release reactions in him for protection against such influences. Thus, receptors for light, smell, taste, temperature, sound, touch, position change, pressure, and tension are at hand which, as parts of the cybernetics system, can release physiologically meaningful protective reactions.
Robust Output-Feedback Based Fault-Tolerant Control of Active Suspension with Finite-Frequency Constraint ★ ★This work is partly supported by Nationa…

Abstract In this paper, the H∞ fault-tolerant control (FTC) problem of active suspensions with finite-frequency constraints is investigated. A full-car model is employed in the controller design such that the heave, pitch and roll motions can be simultaneously controlled. Both the actuator faults and external disturbance are considered in the controller design. As the human body is more sensitive to the vertical vibration in 4-8Hz, robust H∞ control with finite frequency constraints is designed. From the practical perspective, a robust dynamic output-feedback controller with fault tolerant ability is proposed, while other performances such as suspension deflection and actuator saturation ar…
