Exergy surface shaping and thermodynamic flow control of electro-mechanical-thermal systems

International Journal of Exergy (IJEX), Vol. 29, No. 1, 2019

Abstract: This paper extends the concepts and tools of Hamiltonian surface shaping and power flow control (HSSPFC) for electro-mechanical (EM) systems to exergy surface shaping and thermodynamic flow control (ESSTFC) for electro-mechanical-thermal (EMT) systems (i.e., irreversible work processes with heat and mass flows). For this paper, extended irreversible thermodynamics will be utilised to produce consistent thermal equations of motion that directly include the exergy destruction terms. A simplified EMT system that models the EMT dynamics of a Navy ship equipped with a railgun is used to demonstrate the application of ESSTFC for designing high performance, stable nonlinear controllers for EMT systems.
