IIn this paper we propose a robust control for the counter-current heat exchanger. By using energy balance equations, we propose a model in structured bilinear system that allows to capture the heat transfer and convection phenomena. We study the problem of regulating the output temperature of the cold (or hot) fluid by controlling the flow rate of the hot (or cold) fluid. Using an integral action and a forwarding based control method, we derive a non linear control which achieves output temperature regulation. Numerical simulations confirm the effectiveness of the proposed control.
