dragline excavator

System engineering solutions for improving the dynamics of the electric drive of the excavator-dragline based on the fuzzy control model have been substantiated. The design of a fuzzy corrector of the speed regulator of the slave control system of the lifting drive of the excavator-dragline type ESH-15/90 has been carried out. A Simulink model of the proposed electromechanical lifting drive system has been compiled and computer efficiency of the proposed solutions has been carried out.

This article surveys an analysis of dynamic processes of hoist of the excavator-dragline type ЕШ-15/90 using computer simulation, considering the effect of sagging of the rope. A comparison of the accuracy of the obtained computer models with and without the nonlinearity of its elasticity coefficient is considered. Structural models with the use the libraries of MATLAB + Simulink mathematical program are proposed to solve this problem.
