Implementation of PLC for the control of induction motor
(University of Management and Technology, 9/11/2012) Akif, Muhammad; Abdul Sami; Abdul Wahab, Sh.
The use of control systems such as computers to control industrial machinery and processes, replacing human operators, is called Automation. Automation greatly reduces the need for human sensory and mental requirements as well and provides a control without the intervention of human. It provides us the facilities such as moving heavier loads accurately, positioning accurately, moving very fast/slowly, reduced manual handling & improved efficiency. We have implemented Programmable Logic Controller (PLC) for the automation and control of Induction Motor. Programmable Logic Controller is a device that was invented to replace the necessary sequential relay circuits for machine control. It works by looking at its inputs and depending upon their state, turning on/off its outputs. The user enters a program, usually via software, that gives the desired results. Programmable Logic Controller is a user-friendly, microprocessor-based specialized computer that carries out control functions of many types and levels of complexity. Its purpose is to monitor crucial process parameters and adjust process operations accordingly.
