A method to identify physical parameters of a mechanical load with integrated reliability indication includes: applying a first control signal to a mechanical device in a control circuit; measuring a first return signal; and using a power density spectrum of the first return signal to stipulate an excitation signal for the mechanical device.

Robust automatic method to identify physical parameters of a mechanical load with integrated reliability indication

An exemplary control apparatus for an energy distribution system includes a connection to an alternating current supply system and a plurality of predetermined loads each having an energy storage capacity and being electrically connected as by a respective switching device to the alternating current supply system for a duration of a half-wave or a whole number times said half-wave. The respective switching devices are supplied electrical energy from the alternating current supply system for a respective control time period within a predetermined common cycle time period. The start and end of the respective control time periods within the common cycle time period are established prior to the start of said common cycle time period to create a substantially constant loading graph. The optimization procedure is based at least one load in lieu of a continuous control time period having at least two non-continuous block time periods of equal total duration.
