Approaches To Solving Problems Of Optimization Of Solving Monitoring Problems Based On Natural Computing Algorithms, D.T. Muhamediyeva Nov 2020

Approaches To Solving Problems Of Optimization Of Solving Monitoring Problems Based On Natural Computing Algorithms, D.T. Muhamediyeva

Chemical Technology, Control and Management

To find approximate optimization solutions, many algorithms are used, seven of which are considered in this work: fuzzy sets, artificial neural networks, genetic algorithm, ant algorithm, particle swarm algorithm, DNA computation, and a new approach based on artificial immune systems (IIS). All these methods belong to the direction of "natural computing", ie. model certain biological processes, the algorithms of which nature has created for millions of years. It should be noted that the efficiency of one or another algorithm depends on the characteristics of the initial data of the problem, so it is impossible to unambiguously determine which of the …

Neuro-Fuzzy Modeling For Predictive Control Systems With Complex Technological Processes And Production, Yusupbekov Nodirbek, Shukhrat Gulyamov, Malika Doshchanova Feb 2020

Neuro-Fuzzy Modeling For Predictive Control Systems With Complex Technological Processes And Production, Yusupbekov Nodirbek, Shukhrat Gulyamov, Malika Doshchanova

Chemical Technology, Control and Management

The paper implements a modification of a fuzzy neural network, which is suitable for predictive control purposes. Adaptation of a multidimensional programmable controller based on a neural algorithm for the back propagation of forecasting errors is proposed, as well as neural parametric identification of a fuzzy mathematical model of complex technological processes and production based on experimental data and expert estimates.
