Abstract

The aim of the project is to implement cascade control using a Programmable Logic Controller (PLC). The PLC module has been successfully used for ON/OFF control in sequential processes. However in this project the PLC has to be configured to accept and monitor a variable input and to supply a variable output ( 4mA to 20mA) signal in-order to control a final element (e.g. control valve). The significance of this project is to make a comparison between a PLC and a distributed control system (DCS) in terms of controllability and system simplicity. The project requires familiarization in the field of plant process control and instrumentation since it involves the design and implementation of a cascade loop. The cascade controller has been designed to control the level of a liquid in a distillation tower. Familiarization with the PLC hardware and software is another important aspect of the project and took up the bulk of the project time. The final result of the project shows that the PLC is a versatile controller that is able to perform PID control effectively with a relatively simple system. The PLC PID control system is flexible therefore it can be configured to implement any type of control loop e.g. Cascade control.
