ALGORITHMS FOR TUNING OF THE COORDINATING AUTOMATIC CONTROL SYSTEMS
Keywords:Petri net, coordinating automatic control system, coordination of transient processes, ratio control, algorithms of tuning.
Context. The important task was solved during the scientific research related to the development of the algorithm for tuning of the coordinating automatic control system. The reason why the development of those algorithms is important is because of the progress in field of certain classes of complex multilayered control systems, which provide coordination of the transient processes while the regulating technological parameters.
Objective. The purpose of the scientific work is the minimizing of time and the automation of tuning process for the complex multilevel control systems.
Method. We offer the step-by-step tuning of the double-level coordinating systems of automatic control for the refrigeration facilities in the particular for the refrigerating turbocompressor facilities and systems with the tunnel refrigerating chambers. We offer the block-scheme of algorithms which may be used during the realization of automatic search for the system tuning parameters providing coordination of the transient processes under automatic control.
Results. The experiments were conducted in the Matlab 2012a environment. The result of the experiments is graphs of certain transient processes obtained on various steps of the tuning for multilevel coordinating automatic control system. Based on the simulation results we have done the conclusion about efficiency of the different algorithms. The possibility for using of the presented algorithms was also considered, particularly the specificity of the functioning of the automatic tuning of the automatic control multilevel system complex.
Conclusion. These experiments have showed the applicability of certain algorithms of step-by-step tuning for the double-level coordinating automatic control system. It is estimated, that the automatic tuning of the automatic control coordinating systems with algorithm utilization will increase the scope of the modern intellectual technologies.
