MERL seeks a qualified, highly-motivated graduate student for an internship in the area of systems-level dynamic modeling, analysis and optimal control of next-generation thermofluid systems used in heating, cooling and ventilation (HVAC) applications. HVAC systems for applications such as data centers or district heating and cooling are characterized as dynamic networks, described by a large sets of differential and algebraic equations expressing physics (conservation laws), together with discrete and continuous equations describing the action of control. These are large scale, hybrid, constrained nonlinear systems. The MS group at MERL invites qualified graduate students to join its efforts in system level dynamic modeling, analysis and especially control of these systems. The research results are expected to impact both development of new products at Mitsubishi Electric, and also be published in leading conferences and journals.
