Low-Cost Real-Time Vision Platform for Spatial Temperature Control Research Education Developments
Volume 9: 15th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications, 2019
Temperature control is present in many industrial processes, making this skill mandatory for the control engineers. For this reason, different training temperature platforms have been created for this purpose. However, many of these platforms are expensive, require elaborate facility accommodations, and have higher heating and cooling times, making not suitable for teaching and training. This paper presents a low-cost educational platform for temperature control training. The platform employs a Peltier module as a heating element, which has lower heating and cooling time than other thermal system implementations. A low-cost real-time thermal camera is employed as a temperature feedback sensor instead of a standard thermal sensor. The control algorithm is developed in Matlab-Simulink and employs an Arduino board as hardware in the loop to manage the Peltier module. A temperature control experiment is performed to show that the platform is suitable for teaching and training experience...
Development of a low cost thermal feedback system for basic control education
2011
Temperature is a very important industrial parameter and there is a lot of literature available on temperature control. In this paper, we have presented an experimental setup for temperature control of thermal systems. The electronics includes the firing - angle control circuitry to control the AC power to the filament bulb acting as a heating element. The system is identified as first order using the step response method. Different experiments like on-off control, PID control and digital control have been performed on this setup and the experimental results match with the simulation results. This experimental setup is interfaced with the MATLAB using the DAQ card. A GUI is developed in the MATLAB to make this setup user friendly, providing option like gain setting, anti-windup compensator enable/disable, selection of controller type, selection of sampling time etc. The purpose of this paper is to develop a low cost setup to demonstrate control concepts on a thermal system.
Development of a low-cost microcontroller based educational temperature control system
This paper describes the design and development of a low-cost educational temperature control system, developed by the authors at the Near East University. The system has been designed with educational usage in mind, and thus all parts of the system can easily be purchased and constructed in a short time and with little effort. The hardware of the system consists of a popular microcontroller development kit with an LCD, a temperatur sensor device, a fan, and a suitable heating element, all housed in a glass enclosure for easy access to all parts of the system. Using the kit students learn to model the system, and write high-level programs to control and keep the temperature inside the system at the specified value. The results of a survey carried out by the authors is given in the paper, and it was found that students liked to use the developed kit in their laboratory sessions.
Home-made PIC 16F877 microcontroller-based temperature control system for learning automatic control
Computer Applications in Engineering Education, 2011
A closed-loop temperature control system, which is composed of a thermal plant and a controller, has been developed to support undergraduate students in learning automatic control delivered in the Special Topics in Instrumentation Physics course. The thermal plant was made from a plastic box covering a lamp and a fan, which heats and drains the air in the plastic box, respectively, as well as a temperature sensor. The controller with a proportional control action was realized by employing the PIC 16F877 microcontroller. The control signal updates pulse-width modulators (PWMs) in which driver circuits turn on or off the lamp and the fan. A mathematical model of the closed-loop control system was derived and a theoretical transient response was then obtained. It is found that the experimental transient responses were always much lower than the set point and the steady-state errors were high for the proportional sensitivity (K P ) lower than 10. For K P higher than 10, the transient responses tend to approach the set point to cause small steady-state errors. These characteristics are consistent with the theoretical transient response. Further examination revealed that the closed-loop system is a higher order system due to the action of the PWMs and the driver circuits. ß
Design of Temperature Controllers for Industrial Applications using Lab VIEW
LABVIEW technology is used to design and implement the ON / OFF, proportional and PID temperature control system cycle. This covers data acquisition, data storage and data display. An ON / OFF regulator is designed to measure temperature and the digital LABVIEW instrument is used to monitor temperature and ensure temperature does not reach a set point. In industry, feedback control is used to improve and regulate response and the outcome of a number of processes and systems. The development and design of a feedback control system that maintains the process temperature at a predefined set point is discussed in this paper. Using Lab VIEW, an additive, integral and derivative controller is deployed. The developed controller as it integrates PID controllers can have very good accuracy than any other temperature controller.

Development and Simulation of a Low Cost Closed Thermal System to Generate Thermal Cycles through PID Control and IoT Applications, 2020
The aim of this paper is to present the development of a multipurpose device that enables the variation of temperature in a closed chamber with known volume. This system will allow students, researchers and engineers to acquire accurate data and process them in different applications where temperature control is relevant, for example bacterial growth, conservation of biological material, dry air sterilization and other laboratory process. The proposed approach applies proportional-integral-derivative (PID) control loop mechanism, which is widely used in laboratory equipment and industrial control systems. The difference with other systems is, that the one presented here, can be customized using inexpensive components including hybrid digital electronic and analogue actuators. These components can be arranged in different configurations according with a specific need or process. A thermal model was developed taking into account losses and disturbances, and the mathematical model was formulated by finding three different transfer functions for three temperature zones. The first zone covers the range from ambient temperature to 60° C with an actuator (Rb), another actuator for the range from 60°C to 200°C (Ra) and the third actuator (Rc) that covers the range from 0 to-13°C. The data is acquired using an Internet Of Things (IoT) platform.

Design and Implementation of a Temperature Control System
2018
This paper, which features an automatic temperature control system, demonstrates the utility of the controller where no high precision is required, allowing variations between two fixed limits. The temperature control is made in an enclosure made of plexiglas plates thermally insulated with polystyrene to keep the temperature constant over a longer period of time using the Peltier element for the cooling process and thermal resistance for heating. Elements have been purchased based on their price, their efficiency in relation to enclosure dimensions, thermal power, power and supply voltage. The control system also has a user interface where all process parameters can be observed and modified. This is done using the serial connection via USB cable within the LabVIEW development platform.
