Kendali Posisi Linear Actuator Berbasis Pid Menggunakan Plc

Abstract

Linear actuators on pneumatics have a fast linear motion capability, but are not matched with the ability to stop at every position of movement. Linear actuator movement are generally stop at both endpoints. So it is required a control of movement system of actuator linear position. In this study, the authors do research on how to design the control system to control the linear position of the actuator. This research used a PID control system with trial and error method in determining the constant value of PID and used PLC controller. From the test results of the actuator linear position control system, the required time to reach steady state from 0 cm to 30 cm position is 2,079 second. The testing result of linear actuator position control system using PID control gives a small error value of steady state that is 1 mm difference between the target position and the destination position.
