Design of the Fuzzy Control System for the Waste Heat Utilization Plants Driven by the Thermoacoustic Engine

Abstract

The paper addresses the synthesis of fuzzy controllers for computerized control system of the waste heat energy (WHE) utilization plants that operate with the thermoacoustic engine (TAE). Based on the analysis of existing systems, the authors present the main tasks of the synthesized control system, describe its structure and main components. Created system is then tested on the experimental thermoacoustic installation. Using the data obtained authors synthesize the mathematical model of thermoacoustic plant and describe the methodology of its control by the adjustments in resonator length of thermoacoustic device. Using the suggested approach authors design a number of conventional discrete and fuzzy controllers and provide the comparative analysis of quality indicators of the designed control systems transient responses.
