In this paper, we study the Sliding Mode Extremum Seeking (SMES) optimization method for a Heat Exchangers Network. The studied network is constructed from plate Heat Exchangers, in which several thermal sources are used to heat a common cold stream that is distributed between the several branches of the network. The considered optimization problem is the optimization of the thermal power gained from different hot sources. The control variables are the split ratios of the cold stream to the different heat exchangers. The dynamical model for general Heat Exchanger Network with (n) Heat Exchangers was driven and the special case of two Heat Exchangers in parallel was considered as a case study. The SMES algorithm was modified with an integral anti-windup scheme to constrain the search within the admissible region. The simulation results obtained by using Matlab program confirmed the effectiveness of the approach.Index Terms— Heat Exchangers Network, Sliding Mode Based Extremum Seeking, Real-time Optimization.
