The project provides details about the data acquisition unit, the implementation of the controller and also presents test results. ![]() A proportional, integral, and derivative controller is implemented using LabVIEW. The system contains data acquisition unit that gives input and output interfaces in between the PC, the sensor circuit and hardware. This project gives us an idea about the development and design of a feedback control system that keeps the temperature of the process at a predefined set point. Feedback control is used in industry to improve and regulate response and result of a number of processes and systems. A ON/OFF controller system is designed using particular Relay element which controls the heating coil and LABVIEW virtual instrument is used to control the temperature and ensure that the temperature does not go beyond a certain set point. At the initial stage Data Acquisition is replaced by a microcontroller system as a cost effective measure. The project involves includes data acquisition, data processing and the display of data. ![]() The design and implementation of this process is done using LABVIEW, virtual workbench software. ![]() ![]() This work describes a framework of ON/OFF, proportional and linear temperature control systems.
