| Summary: | 碩士 === 逢甲大學 === 資電碩士在職專班 === 103 === The content of this thesis is to investigate the energy-saving methods of elevator controller systems. From the progress of conventional controlling speed methods, it can be used to improve the main-motor controlling efficiency. By means of motor structures and control theorem, we will use the frequency conversion technique to investigate the saving-energy reason and to recycle the unused rising-up-voltage energy. We also use the fuzzy control theory to improve the operating efficiency of the dispatching system of an elevator and to increase the sleep-saving-energy efficiency.
In this thesis we proposed a novel technique of dynamic loading capacity variation based on the principle of conservation of energy and the balancing operation of 50 % loading. If every running of an elevator is the balancing operation, it not only requires the minimum electrical power and but also creates the minimum rising-up voltage for achieving the destination of saving energy.
The key technique of saving energy for an elevator depends mainly on operating the facilities of control system. For the user to operate an elevator with the time and voltage/current, and button-level etc. to be recorded, the fuzzy control theory is used for finding the fuzzy controlling flag and then to tell elevator’s control unit to operate the saving-energy model operation. We also use the optimum saving-energy operating experience of 50 % balancing loading of an elevator and the dynamic varying rated-loading for reaching the maximum saving energy.
Keywords: elevator control system, saving energy, frequency conversion technique, rising-up voltage, fuzzy control, control flag, and dynamic loading-capacity.
