Improvement of automation in managing thermal destruction of municipal solid waste through software recovery from failures

Abstract

The article presents the results of improving automation in managing the thermal destruction of municipal solid waste (MSW) through software recovery after failures. A functional structure and selected technological parameters (as controlled coordinates) for a hierarchical automatic control system (ACS) for MSW thermal destruction were proposed. A homogeneous Markov chain was used to model the failure and fault parameters of cyclic software operation. The application of the ACS with the proposed recovery structure ensures software reliability by adjusting the threshold number of failures. This recovery implementation reduces environmental pollution in stationary modes with known raw material composition, in dynamic modes with material composition changes, and during pyrolysis plant start-up. The proposed approach enhances the accuracy of controlling key technological parameters, operational reliability, and economic performance.
