Abstract:
A system and method reduce lateral movement of a car in an elevator system by detecting vibration of the car as a vibration signal. A damping coefficient for a feedback signal is determined according to the vibration signal and a state of the elevator system. A semi-active actuator is arranged between the car and a roller guide assembly. The semi-active actuator includes a rheological fluid, and flow characteristics of the rheological fluid are actuated according to the feedback signal to reduce the lateral movement of the car.
