Optimization model controlling parameters of a roller drilling process based on energy criterion

摘要

The article is concerned with development and research of an optimization model controlling parameters of a roller drilling process using correcting values of operating parameters. The optimization model proposes the use of an energy criterion that provides the ratio of performance and drilling bit resource, corresponding to the minimum cost of a roller drilling process. The proposed model allows to determinate the optimal values of the technological process operating parameters, as also the maximum values of the drilling bit resource and performance under the information uncertainty associated with an unpredictable change in the properties of drilled rocks, which is necessary for the effective control of the process parameters under research.
