Design and Development of Control System for Railway Cable Laying

In this work is studied the automation of a railway cable laying system using a PLC as regulator, where the objective is to keep as stable as possible the stress of the cable being laid. As the system was completely manual, a previous work has been needed in order to set both sensors and actuators so that the system can be electrically controlled. Different tests were done in order to find out the relationship between the different variables, and to propose a regulator algorithm according to these. The obtained results show that the system is properly automated via PLC using the designed regulator.
