Robust Control for the Hybrid Energy System of an Electric Loader

With the wide application of electric vehicles and development battery technology, pure construction machinery (PECM) has received more attention due to its high efficiency no pollution. The working conditions are complex accompanied by periodical heavy load. For machinery, a load represents an energy supply with large current. To adapt PECM, this paper proposes robust controller regulate current hybrid system (HES) which include supercapacitor. V-type operating 5-ton loader research focus analyze principles HES. topology flow patterns HES proposed analyzed. model battery, supercapacitor, DC/DC converter depicted, control method is designed. An experiment platform created verify effectiveness method. Compared proportional integral effect, results show that had good performance could better It can be used as reference value for other dual source PECM.
