During the gas turbine engine operation, it is necessary to continuously monitor many different parameters. Now, to solve this problem, a selective regulator is used, which, when the parameters deviate from the norm, controls the dispenser influencing these technological values. With this method of control, the engine elements wear out quickly, and the control accuracy remains low.
“During operation, the requirements for the characteristics of the engines may change. If the controller is designed for one setting parameters, then over time it will cope with its task worse. Such a mechanism requires constant correction of embedded algorithms, which increases the cost of its maintenance. Our regulator is more adaptive, it “adjusts” to changing environmental conditions, which makes it a universal control tool”, says one of the developers, Sergey Storozhev, graduate student of the Department of Automatics and Telemechanics of the Electrical Engineering Faculty of Perm Polytech .
The development of scientists is based on the analysis of the “traveled path” of each input variable. The input variables are the signals coming from the sensors, and the output ones are the control signals for the temperature and speed of the engine elements. It is possible to improve the quality of control by measuring and analyzing all the components that are part of the structure of a turbojet engine. To do this, scientists have applied a multi-agent approach, in which an unlimited amount of input data can be used when calculating control actions.
“The new regulator will significantly reduce the uncertainty in the operation of the combustion chamber of the engine, ensuring guaranteed thrust of the aircraft. The development will help improve the reliability of the aircraft engine. At the same time, it is possible to reduce hardware costs and the time of regulation”, explains the developer.
In the near future, researchers from Perm Polytech are planning to conduct tests in real conditions, which will be held at the site of one of the industrial companies of the Perm Region.
