Fuzzy Control for Reduction of Acceleration and Vibration of a Stretcher-Cart on an Ambulance

抄録

When an emergency car carries a dangerous object or a patient in critical condition, it should provide safe conveyance, free of swaying and swinging. But while the car (i.e.an ambulance or an emergency vehicle) is running, these movements cannot be actually reduced by passive control using springs and dampers. Therefore, we employ fuzzy control to reduce the acceleration and vibration which a patient (object) receives on the ambulance, on the basis of the driver's knowledge. For this, we use fuzzy control rules which consist of two protection rule sets, one for the forward and backward directions, and another one for the lateral direction. Also, we use two different fuzzy control algorithms (i.e.approaches ) the indirect fuzzy control method and the direct fuzzy control method.
