Abstract: Heat exchanger system is widely used in chemical plants because it can sustain wide range of temperature and pressure. The main purpose of a heat exchanger system is to transfer heat from a hot fluid to a cooler fluid, so temperature control of outlet fluid is of prime importance. To control the temperature of outlet fluid of the heat exchanger system a conventional PID controller can be used. Due to inherent disadvantages of conventional control techniques, Fuzzy logic controller is employed to control the temperature of outlet fluid of the heat exchanger system. The designed controller regulates the temperature of the outgoing fluid to a desired set point in the shortest possible time irrespective of load and process disturbances, equipment saturation and nonlinearity.

Abstract: The goal of this paper is to consider a co-design approach between the controller of a process control application and the frame scheduling for CAN-Based Networked Control Systems in order to simultaneously improve the Quality of Control (QoC) of the process control and the Quality of Service (QoS) of the CAN-based network. First, we present a way to calculate the closed-loop communication time delay and we compensate this time delay using the pole-placement design method. Second, we propose a hybrid priority scheme for the message scheduling which allows to improve the QoS. Finally, we present a co-design of the communication time delay compensation and the message scheduling, which gives a more efficient Networked Control System
