Abstract

By the example of the D.C. motor with independent excitation, the optimization of positional electric drive tachograms by criterion of a minimum of electric losses in anchor chain during the process of adjustment the specified displacement discontinuities with a rated magnetic flow. The comparative analysis of triangular, parabolic and quasioptimum trapezoidal tachograms was carried out. Parameters of the modes "minimum minimorum" and a zone of rational change of acceleration for a variation of movements time was determined. Using the generalized criterion of electromechanical transformation of energy, the energetics of positioning electric drive when the moment of resistance to motion is near to zero was investigated.

Keywords

Position electric drive, optimal tachograms, quasioptimum control, criterion of electromechanical transformation.
