Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Mathematical model of the nonlinear heat transfer system with delay A.A. SHILIN V.G. BUKREEV K.I. KOYKOV The mathematical model of the nonlinear heat exchange hot water system with delay is obtained. For fixed parameters of system elements and determined nature of related thermal processes, mathematical model of the object is represented as a system of nonlinear differential equations in the form of Cauchy. Simulation model of the system is built in Simulink. The results of the comparative analysis of simulation and experimental studies reflect a good value for the proposed mathematical model of heat transfer to the real processes occurring in the facility.
