Abstract: A guide device (26) for use in an elevator system includes an elevator guide roller (30) having a hardness that varies depending on a speed of rotation of the guide roller (30). In a disclosed example, a magnetorheological fluid within the guide roller (30) changes viscosity depending on the speed of rotation. One example includes varying an influence of a first magnetic field on the magnetorheological fluid to change the viscosity.

Abstract: In an elevator apparatus, an actuator for generating a vibration-damping force against the lateral vibration of a car is provided in parallel to elastic member for preventing the lateral vibration of the car. The actuator is controlled by a vibration-damping control unit. The vibration-damping control unit estimates a natural frequency of the lateral vibration of the car, determines a gain value on the basis of the estimated natural frequency and a rigidity value of the elastic member, and drives the actuator in accordance with an instruction signal obtained by multiplication of the determined gain value.

Abstract: In an elevator, guide devices are attached to the elevator and include a guide lever driven in a plane; a guide element attached to the guide lever; a stationary actuator part fixed to a support member; and a moving actuator part fixed to the guide lever, wherein a first part of the moving actuator part and the stationary section is a magnet that generates a magnetic field crossing a driving direction of the moving actuator part, a second part of the moving actuator part and the stationary section is a coil wound around a bobbin which is arranged so that it is influenced by the magnetic field and drives the movable section of the actuator in the driving direction of the movable section of the actuator. The magnetic field is generated by an electric current flowing in the coil when the elevator car is vibrated.

Abstract: An improved centering control for an elevator horizontal suspension having at least one actuator and includes a circuit for disabling the control or braking the actuator in response to an error signal indicative of the difference between a reference signal and a sensed signal indicative of the degree of centering of the car. Of course, both braking and disabling may be carried out instead of just one. For those cases in which two actuators are acting in concert to center the car, where the control is responsive to the error signal for only selecting one of the opposed actuators at a time, a small centering window is set up about the centered condition and part of the window is used to disable or brake one of the actuators and another part to disable or brake the other of the actuators. Again, both disabling and braking operations may be carried out at the same time with respect to a given actuator. For a centering control in which opposed actuators are used with individual feedback control loops to achieve a preselected preload, the improved control only uses the feedback loop when the corresponding actuator is unselected for actuation.

Abstract: A set of semi-active actuators is arranged in an elevator system to compensate a vibration of an elevator car. The actuators are controlled in accordance with the control policy based on a measured signal including values of the parameter measured during the operation of the elevator system. The control policy is determined, based on a model of the elevator system, wherein the control policy includes a state function representing an operation of the elevator system and a function of displacement representing an operation of the set of semi-active actuators. The state function is approximated, using the model of the elevator system, as a first function of a parameter representing the vibration. The function of displacement is approximated, using the model of the elevator system, as a second function of the parameter.
