Abstract
A method controls a set of semi-active actuators arranged in an elevator system represented with a model of a virtual elevator system having a single virtual semi-active actuator arranged to compensate a virtual disturbance proportional to a sum of disturbances from the set of disturbances. The method determines the virtual disturbance during an operation of the elevator car using a motion profile of position of the elevator car during the operation and a disturbance profile of the virtual disturbance, and determines amplitude of a virtual force of the virtual semi-active actuator using the model and the virtual disturbance. A gain of a controller for controlling the set of semi-active actuators is adjusted based on the amplitude of the virtual force and a reference force of the virtual semi-active actuator.
