Abstract

The goal is to increase the efficiency of the mining combine by improving the algorithm of automatic control of the speed of movement of the executive body. The main criterion for the quality of the control process is to ensure the minimum time of the transient process at the output of the control system, provided that the level is not exceeded by over-regulation of 10%. Methods. The methods of the theory of automatic control, as well as system analysis, were used to study the systems of automatic control of the speed of movement of the executive body of the mining combine. The research was conducted on the basis of computational experiments using computerized methods of system synthesis. Evaluation of the effectiveness of the automatic control process was carried out using the methods of mathematical statistics. The results. It was established that for each functional mode of movement of the combine's executive body in the regularities of changing of the criteria of the efficiency of the transition process, when the parameters of the regulator are changed, taking into account the restrictions on the criteria, the minimal extremes are presented, that correspond to the optimal settings of the regulator. At the same time, for each functional mode of movement of the executive body of the combine, these extremes occur for different combinations of values of the parameters of the speed controller of the movement of the executive body. Practical meaning. The revealed regularities regarding the dependence of the quality criteria of the automatic control system on the parameters of the speed regulator of the executive body of the mining combine will allow to take into account the variability of the properties of the combine as an object of automatic control in the control algorithm of modern regulators, and due to this increase the productivity of the combine and reduce the ash content of coal due to more accurate working out of coal seam hypsometry.
