ENERGY REPRESENTATION VIA DESIGN FUNCTION STRUCTURE FOR MULTI-ATTRIBUTE OPTIMIZATION OF TRACTION ELEVATOR SYSTEMS
The concept of a new design method for energy-efficient electromechanical systems is proposed. According to that, the function structure of a system represents the energy flows and conversions performed between its subfunctions. A systematic procedure leads to the design parameters that affect the energy consumption for its basic function. These are correlated with the parameters that affect service performance. The values of all that parameters are defined by computational intelligence methods so that optimum overall efficiency is obtained. Traction elevators are used as a case study.
