Abstract:
Traditionally, the auto plants had to be shut down for up to a month at model changeover time. The hardwired planes were very time consuming to wire, debug and change, for these reasons used in this project Programmable Logic Controller (PLC). The PLC keyboard reprogramming procedure replaced the rewiring of a panel full of wires, relays, timers, and other components. The new PLCs helped reduce changeover time to a matter of a few days.
Programmable Logic Controller (PLC) is specialized computer used to control machine and process, The PLC performs the logic functions of relays, timers, counters and sequencers.
In this project design Hydraulic pump using PLC has Proportional Integral Derivation Controller (PID) control faster what are able to accomplish process control effectively using ladder diagram.
The reason for used the PID to provide the stability and less error for many times because, the characteristics of the elements or components may change following the time eclipse and the controlling process may be affected by the change of loading or external disturbances. The simulation results show that the performance of the hydraulic pump is good.
