Automation of primary crushing control

Abstract

The article deals with issues related to the synthesis of an automatic control system for a jaw crusher, for which the main control and disturbance channels were identified and its mathematical model was obtained. Implementation of mechanization and automation systems at crushing and screening plants is necessary for the production of granite crushed stone, which is massively used in the construction of agricultural facilities. Based on the analysis of the mathematical model, a decision was made to choose the law of regulation and its parametric identification was carried out. Analysis of the quality indicators of the regulation of the synthesized system revealed their significant dependence on the disturbing effect, which required the synthesis of a disturbance compensator, the inclusion of which in the structure of the system made it possible to realize the requirements imposed on it.
