ABSTRACT:
An elevator control system for operating the cage of an elevator wherein the cage is run from one floor to the next floor at which it is to be stopped with a minimum amount of energy consumption. Energy consumption estimating circuits produce estimates of the amount of energy required for the cage to run to the next floor at which it is to be stopped for a plurality of different maximum cage speeds. The outputs of the energy consumption estimating circuits are coupled to a minimum value selecting circuit which determines which of the energy consumption estimating circuits has produced the lowest estimate. The elevator cage is then run at a speed profile and at a maximum speed chosen in correspondence with the minimum energy consumption.
