On the Energetics of a Mechatronic Elevator System

Abstract

The energy balance equation consisting of mechanical and electrical parts of a mechatronic elevator system is studied in this paper. The total input energy is equal to the mechanical and electrical energies, where a weighting factor should be added for the mechatronic system. The calculus of variation is implemented to find the minimum input electrical energy control (MIEEC) and minimum dissipation energy control (MDEC), which are compared and found to have the same results. From numerical simulations, it is confirmed to demonstrate that the energy balance equation must contain a weighting factor in a mechatronic system.
