PURPOSE: To certainly grant optimum stop property to an elevator by simulating the operation of an elevator driving system and repeating a series of operations until model parameters and control parameters are converged. CONSTITUTION: A simulation driving sequence TU for wideband noise is input from a unit (AE)2 to an elevator system (ES)1 via a switch SW to measure its response speed with a rotating speed meter (T)3, find a mathematical model M using a driving sequence I and a speed O as stating data with a unit (RLS)4, simulate the operation of the system ES and find a control parameter value C by optimizing a value for the model M with an optimizing unit (TO)5. A position control device (PID)7 inputs the optimum control parameter C from an adjuster 6 for adjustment, inputs an actual driving signal NO to the elevator system (ES)1 via the SW, and reevaluate the model parameter to be repeated until they are converged. In this way, accurate stop at a target level is achieved. |
