摘要：
A method and apparatus for counteracting a disturbing force acting on an elevator platform in a hoistway comprises sensing the acceleration and position of the platform and applying a force between the platform and the hoistway in proportion to the magnitude of the acceleration signal, in proportion to the integral of the acceleration signal and in proportion to the position signal. The second position signal may be obtained from an electromagnet actuator wherein the sensed current may be divided by a sensed flux density signal multiplied by a transformation signal to obtain position. A force feedback signal may be obtained by squaring the flux density.
