description: The purpose of this final qualification work is the calculation and design of an automatic control system for turning the excavator tower. This work will be useful in studying the issues of calculating automatic control systems with machine or throttle control and having a rotational character of movement of a loading object.
The paper presents the energy calculation of the power and control cascades of the automatic control system with the choice of the main hydraulic equipment for them (the choice of the pump and the hydraulic actuator), and their static characteristics are constructed. The transfer function of the open loop of the system is compiled, on the basis of which the dynamic characteristics are built. Based on the obtained dynamic characteristics, the system is analyzed for stability and accuracy. In order to fulfill the requirements of stability and accuracy, a sequential correction was carried out. The transition process is investigated and its assessment is made (its nature and duration).
As a result, a stable tracking electro-hydraulic system for turning the excavator tower, satisfying the requirements of the task, was designed.
