ABSTRACT OF THE DISCLOSURE 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 compensa- tion, to a function which provides a response in accord- ance 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 recip- rocal of the desired transfer function is not required.
