Modeling and Investigating Dynamics of the Electric Drive of Excavating Machines Swing With the Use of the Combined Optimal Control System 000_3.pdf

Improving quality of the automated electric drive is one of the most efficient and cost-effective ways to improve reliability and durability and to reduce down time in repairing mining complexes. currently in Russia, the excavator park has tens of thousands of machines, about 80% of them are exhausted that leads to the need of repairing works. The rotary mechanism electric drive ring gear repair cost is calculated to be 30-40% of the total excavator cost. Optimizing the rotation drive control reduces the dynamic load of a ring gear. Reducing the dynamic load is carried out with the electrical part of the drive that improves reliability and durability of the system. Therefore, the creation of automated electric drive control systems requires the use of mathematical models. The authors consider the rotary electric drive with the highest number of failures in mechanical and electrical parts of the excavator, with a combined optimal control system representing the voltage inner circuit and the optimal regulating device constructed analytically with the highest number of the anchor chain current, engine speed, elastic time, and speed of the second mass located in the forward channel of the control system. In order to investigate the drive, the simulation model was created in MATLAB program with the use of simulink package.
