T-S Fuzzy Algorithm Optimized by Genetic Algorithm for Dry Fermentation pH Control

نویسندگان

چکیده

In the process of anaerobic dry fermentation to produce biogas, maintaining a suitable pH in environment is more conducive degradation crop straw. When too low, digestion by bacteria inhibited. Therefore, it necessary quickly adjust pH. this work, we studied control technology regulation system and then constructed T-S fuzzy controller. Upon simplifying controller, delay time was reduced, two genetic algorithms with different fitness performance indicators were used optimize control. The simulation experiment study designed through software, results show that improved method has fast ability. Finally, on-site experiments conducted using four methods under acidification conditions set experimental device. improve integrating error sum squares short small oscillation overshoot, can better regulate environmental achieve appropriate when occurs during fermentation.

A practical algorithm for [r, s, t]-coloring of graph

Coloring graphs is one of important and frequently used topics in diverse sciences. In the majority of the articles, it is intended to find a proper bound for vertex coloring, edge coloring or total coloring in the graph. Although it is important to find a proper algorithm for graph coloring, it is hard and time-consuming too. In this paper, a new algorithm for vertex coloring, edge coloring an...
