Abstract
A method controls a set of semi-active actuators arranged in an elevator system to minimize a vibration of an elevator car. The elevator system is represented with a model of a virtual elevator system having a single virtual semi-active actuator arranged to compensate a virtual disturbance. The virtual disturbance is determined using a motion profile of position of the elevator car during the operation and a disturbance profile of the virtual disturbance. A state of the elevator system is determined using the model of the virtual elevator system, the virtual disturbance and a signal indicative of a horizontal acceleration of the elevator car during the operation. Each actuator of the set of semi-active actuators is controlled based on the state of the elevator system and according to a control policy of the virtual semi-active actuator.
