Analiza cyfrowa wpływu zakłóceń stochastycznych na prędkość kątową w układzie napędowym prądu stałego przy zastosowaniu języka SESL

Abstract

The paper presents the results of the simulation analysis of the stochastic disturbances on the angular velocity of a d.c. drive. The three main problems concerning the control systems were discused. a) P - type speed controller and PI current controller, b) P - type speed controller and PI current controller and time delay of the thyristor rectifier, с) with the PI speed controller and PI current controller. The analysis was carried out basing on the SESL simulation language, with FORTRAN proceders generating the stochastic processes and proceders determining the probabilistic characteristics of control signal and angular velocity in these structures of driving systems. The coefficients of filtring systems of same control systems of drives was evaluated as well.
