ABSTRACT:
A method of generating a landing speed pattern which starts with the dynamics of the actual elevator system and the desired actual landing velocity profile curve, and generates a landing speed pattern which will produce the desired actual landing velocity characteristic. In a preferred embodiment, the actual desired landing velocity is a function of time squared, defining a parabolic profile. The apparatus includes arrangements for implementing a predetermined speed pattern equation in response to the distance-to-go count (DTG) of predetermined standard increments to the target floor.
