Abstract. The article presents a functional diagram of the control subsystem of the electric drive of a walking excavator. Structural-parametric models of АC electric drives of an excavator with a pulse-phase control system and a pulse-frequency control system have been developed. Simulation of АC electric drives of an excavator with a pulse-phase control system and a pulse-frequency control system in the Matlab/Simulink environment was carried out. A comparison of the results of modeling control systems is given.
