Optimization of two–mass electromechanical system
Abstract
The issues of two – mass electromechanical optimization are analyzed. The probable methods of optimization and measures were discussed. The structural diagram of system optimization is presented, it is comprised of DC motor with two – mass mechanical link Matlab/Simulink model, PID regulator and units of signal limitations. The optimization process is finalized, when the characteristics of transitional process corresponding the proposed parameters are derived. The results obtained indicate that after determining the optimal values of the amplifying coefficients for the regulator during the optimization it is possible significantly reduce the oscillations of drive velocity, acceleration, current and torque and obtain optimal dynamic characteristics. Nagrinėjami dvimasės elektromechaninės sistemos optimizavimo klausimai, aptariami galimi optimizavimo būdai ir priemonės. Pateikiama sistemos optimizavimo struktūrinė schema, kurią sudaro DC variklio su dvimase mechanine grandimi Matlab/Simulink modelis, PID reguliatorius ir signalų apribojimo blokai. Optimizacijos procesas baigiasi, kai randama nustatytus užduotus parametrus atitinkanti pereinamojo proceso charakteristika. Gauti rezultatai rodo, kad optimizavimo metu suradus reguliatoriaus stiprinimo koeficientų optimalias vertes, galima gerokai sumažinti pavaros greičio, pagreičio, srovės bei momento švytavimus ir gauti optimalias dinamines charakteristikas
