“…The example application for the heat distribution system has been reported e.g. by Paruchuri and Rhinehart, [25]. There are also the survey articles that report the comparison among different advanced control strategies in the practical applications for different systems including the local control in the heat distribution systems, see e.g.…”

“…Manipulation of the non-controlled stream is also used in the work of Paruchuri et el. [5], in which a process-model based controller is experimentally demonstrated for control of tube-side outlet temperature in a steam/water heat exchanger. Studies of heat exchangers with a bypass can similarly be found in literature.…”

This thesis addresses temperature control of an engine bleed air system, as used on typical aircraft, with a control strategy aimed at reducing ram air usage while maintaining fast response. The analytical equations describing the system dynamics are presented, and a state space model of a cross-flow heat exchanger is developed. The heat exchanger model is then utilized in the modeling of the bleed air system under study. Different control strategies and configurations are analyzed and compared. In order to achieve fast temperature regulation while saving ram air usage, a ram-air-plus-bypass control configuration is proposed, along with the control of both load temperature and bypass valve opening. Classical PI control is employed, and a hybrid LQ/PI control method is additionally investigated for the proposed control configuration. Simulations for each control strategy are performed using a nonlinear dynamic model at several sample mission operating points, with consideration of disturbances in engine loading of ambient conditions. Comparisons are made and conclusions are drawn based on these simulations. The proposed configuration and control strategy prove to be more effective in terms of satisfying both low ram air usage and fast temperature control response.
