An energy-saving overload-control technology based on a computerized training-machine system

Abstract

Energy-efficient control of electric drives of an overload machine and operator training for a computerized practice-machine system (CPMS) are considered. The energy consumption of an overload machine depends on the kind of control actions taken by the operator and dynamic characteristics and modes of use of the drives, which has to do with the level of the operator’s professional training. Unreasonably abrupt accelerations and hard braking increase the wear of electromechanical equipment and lead to additional electricity consumption. The energy-saving technology of overload machine control is based on presenting the operator’s work as a functionally complete set of tasks (practice exercises) formally presented as a set of tasks for optimal electric-drive control. The solution of these tasks forms a system of wanted paths and controls used as advising actions in the practice-machine system when doing a set of practices. The results of designing a computerized simulator system (CPMS) for overload machine operators are presented. The training in this system makes it possible to form skills of energy-saving control over process equipment. The operator forms his sensory motor skills in the CPMS by doing a set of practices to simulate the actual technological operations of the overload process. The CPMS is designed to accumulate, store, and process data on the acquisition of professional skills and expertise by a trainee. The structure of the skill-formation control system is given as a component of the CPMS, and its connection with the computerized simulator (overload modeling unit) is also considered.
