Abstract— Shell and tube heat exchanger is widely used in industries because it can withstand over wide range of temperature and pressure. The function of shell and tube heat exchanger is to transfer heat from hot fluid to a cooler fluid, so the temperature control is the prime purpose. In general, temperature control system has the characteristics of non-linearity, large inertia and time variability so to overcome the effects of these factors and get the satisfactory results by using normal PID controller. To control the temperature of output fluid of the heat exchanger system a PID controller, FOPID controller is used in this paper. The controllers are implemented in this paper based on comparative analysis to control the output temperature of heat exchanger system. In addition to that optimization through GA technique will be implemented in this paper later for better effective temperature control.

Firstly a classical PID controller is implemented to achieve the control objectives. PID controller exhibits high overshoots which is undesirable. To minimize the overshoot FOPID controller is implemented. FOPID based controller has gained widespread acceptance because of its robustness; it has five parameters to tune instead of three. In this paper three types of controller are designed to achieve the control objective and a comparative study between the controllers are evaluated

Building Control Nvq
116 Words | 1 PagesBuilding control is an important aspect to consider whilst in the construction process; if the approved inspectors and the CIOB do not inspect the work being done then the workers will not know if they are doing something wrong. The reason in which building control is important is that the inspectors can make sure that everyone is complying with building control. The regulations that are implemented exist to ensure the health and safety in and around all types of buildings they also provide for energy conservation and access to and use of buildings. The building regulations contain various sections dealing with definitions, procedures and what is expected in terms of the technical performance of building work.
Ece/532 Technical Paper
1117 Words | 5 PagesSince the heat transfer process is sensitive to both velocity and temperature of the air, any changes in temperature must be compensated in order to achieve accurate mass flow measurements. Hence Fuzzy Temperature Compensation scheme (FTCS) is employed to compensate the measurement error that might occur due to this sensitivity. In this case study the FTCS is used to compensate the error occurred by using sugeno type Fuzzy inference for temperature ranging from 60-100 0C. In order to verify this proposed compensation scheme first a simulation model is developed using Matlab/Simulink. Then the algorithm for FTCS is developed using c programming language and implemented in hardware based real time using digital signal controllers.

According to Figure 2, A1 and A3 are deception attacks where it sends false data which includes incorrect time, incorrect measurement or incorrect sender id. The adversary can send the data through a secret key or by compromising

Kilimanjaro By the middle of 1996 Thermo’s keen instruments were already noticing that a warming trend had recommenced across the planet as he was flying around collecting data, which was disturbing to Dr. Carson and many of his colleagues. Data was beginning to indicate that most glaciers were receding world-wide. Carson wanted Thermo to take his first flight over the famous Mount Kilimanjaro in Tanzania, Africa where climatologists had been noted changes in ice covering the upper portion of that volcano for decades.

Decentralized Control Design
1469 Words | 6 PagesThe MIMO control design of such a system requires a complicated mathematical model of musculoskeletal dynamics in the control law design, so to reduce the complexity of the controller a decentralized control scheme is used. The decentralized control problem is to design a set of independent controllers in which each subsystem is controlled by an independent controller. The interaction between the subsystems is taken as external disturbances for each isolated subsystem

Steam Ejector
1742 Words | 7 PagesAs shown, the system COP could achieve 1.259 when Tg = 40 °C and Te = 15 °C. When the evaporating temperature was 15 °C, the system COP was much higher than that when the evaporating temperature was set at 10 °C. But the system COPs were almost the same when Tg = 65 °C. In other words, the cooling capacities were nearly equal when Te = 10 °C and Te = 15 °C at this condition. When Te = 15 °C, the cooling capacity decreased first and then increased with the generating temperatures ranging from 40 °C to 70 °C.
Emmett Teller Analysis
873 Words | 4 PagesFor controlling the heating temperature of the catalyst presence in a reactor is done by a micro-processor based temperature controller. The gaseous products are produced after the oxidation reaction in a reactor is analysis by an online gas chromatogram (Nucon series 5765) equipped with a porapack q-column, FID detector and a methaniser for measuring of the concentration of CO and CO2. The oxidation of CO at any instant was calculated on the basis of concentration CO in the feed and product stream by the following equations: (XCO) = [(CCO)in - (CCO)out ] / [CCO]in = [(ACO)in - (ACO)out ] / [ACO]in --------------- (2) Where, the concentration of CO is proportional to the area of chromatogram ACO.
