“…In [4], a dynamic behavior identification of a through-flow heat exchanger was proposed and a self-tuning predictive was designed. The internal model based PID controller proposed in [5] to provide a satisfactory performance for the heat exchanger in both steady state and transient state. A simple bounded positive control system for heat exchangers was proposed by [6].…”

The heat exchanger is a device used to transfer heat energy between two fluids, hot and cold. In this work, an output feedback adaptive sliding mode controller is designed to control the temperature of the outlet cold water for plate heat exchanger. The measurement of the outlet cold temperature is the only information required. Hence, a sliding mode differentiator was designed to estimate the time derivative of outlet hot water temperature, which it is needed for constructing a sliding variable. The discontinuous gain value of the sliding mode controller is adapted according to a certain adaptation law. Two constraints which imposed on the volumetric flow rate of outlet cold (control input) were considered within the rules of the proposed adaptation law in this work. These are the control input is a positive quantity, and it limited by a maximum value. The maximum allowable desired outlet cold water has been estimated as function of heat exchanger parameters and maximum control input. The simulation results demonstrate the performance of the proposed adaptive sliding mode control where the outlet cold water was forced to follow desired temperature equal to 45 . Additionally, the robustness of the proposed controller was tested for the case where the cold water inlet temperature is not constant, and also for the case of heat exchanger parameters uncertainty. The results were revealed the robustness of the proposed controller.

“…In the 'Shell-andtube' type heat exchanger one fluid passes through the tube and a second fluid passes through the space between the shell and tube. The heat transfer surface to volume ratio is very large as compared to coiled type and double pipe type of heat exchanger system (Padhee et al, 2011). Shell and tube type heat exchanger can be easily manufactured in large size and configurations.…”

“…The actuator unit converts the controller output in the range of 4-20 mA in to a standardized pressure signal of the range of 3-15 psi. The control valve actuates according to the controller signal and control valve allows the needed steam to enter in shell-and-tube heat exchanger as to maintain the outlet temperature of heat exchanger system (Ismail et al, 2015;Duran et al, 2008;Padhee et al, 2011). Mainly two types of disturbances are present in shell-and-tube heat exchanger system; first one is variation in input fluid flow (Q m ) and second is variation in input fluid temperature (θ i ).…”

This study analyzes the performance of shell and tube type heat exchanger system using different controllers like PID controller, fractional order PID controller and fuzzy controller. The main purpose of a controller is to control the outlet temperature of a shell and tube type heat exchanger system to a particular set point value. The steady state performances of different controllers are analyzed with and without load disturbances to find out the best controller. The MATLAB simulation results exhibit that the fractional order PID controller gives low peak overshoot and low settling time when compared with PID controller and fuzzy logic controller.

“…The outlet temperature of the heat exchanger system has to be kept at a desired set point according to a process requirement. Firstly a classical PID controller [1] is implemented in a feedback control loop so as to obtain the control objectives. To further optimize the command performance, feed-forward controller is utilized in conjugation with the PID controller.…”

Heat exchanger system is widely used in chemical process industries, including petroleum refining and petrochemical processing, especially in the hazard zones because its convert the fluid from high range of temperature and pressure from the storage tanks to the pipe lines. A heat exchanger consists of two main modules, the first module is mechanical (vessel, shell, tube) It happens inside heat transfer, the second module is the controller circuit which controls the mechanical module by opening and closing the valves according to the set point temperature. This paper will focus on improving the performance of control circuits which is used in the heat exchanger. Genetic controller will replace the PID and the Fuzzy controller to obtain the best solution. As a consequence, the overshoot ratio and the settling time is reduced to 0.03% and 110 seconds respectively.
