Abstract. A control system developed for liquid heat exchanger in hop extract production is presented. A robust controller based on the sliding mode method and the full-order Luenberger observer is implemented. A comparative analysis of this method and the PID control method using pulse-width modulation under conditions of disturbances, noise and quantization of measurements is carried out. Simulation results confirming the advantages of the proposed approach are presented.
Keywords: heat exchanger, hop extraction, control system, PID controller, sliding mode method
