    Abstract: An elevator system having an elevator car and a drive system for operating the elevator car. The drive system is forced to adaptively appear to have a desired transfer function in response to a speed pattern signal. In one embodiment, the speed pattern signal is developed by applying the ideal speed pattern, without lag compensation, to a function which provides a response in accordance with the reciprocal of the desired transfer function. In another embodiment, the speed pattern signal is the ideal speed pattern, with lag compensation, and the reciprocal of the desired transfer function is not required.

    Abstract: An elevator system in which the movement of the elevator car is responsive to a comparator which provides an error signal responsive to the difference between the magnitude of a speed pattern signal provided by a speed pattern generator, and a signal responsive to actual car speed. An adjustable impedance device controls the affect of the speed pattern signal on the comparator, with the impedance of the adjustable impedance device being responsive to at least one predetermined parameter of the speed pattern signal.
