Electro hydraulic servo system is used by many industries due to its ability to impart large forces.
It also has advantage in term of fast response and robustness. The electro hydraulic system suffered
from errors of the transient response which are steady state error, settling time and the ripples. It
is crucial to design a controller for the system to ensure the reliability of the system. Aiming at the
characteristic of the system, steady state feedback control method is designed to compensate the
error. The analysis of the system is done based on the transient response specifically on the actuator
part. MATLAB Simulink is used as the simulation software to evaluate the force performance of
state feedback controller method. The steady state error, settling time and ripple are observed and
recorded for each controller. Three methods is applied, which are full feedback, state feedback with
feed forward and integral control are compared with proportional, integral and derivatives (PID)
controller. The result of each controller shows the differences performance. Based on the simulation
results, the feedforward technique is found to be the best control technique for the electro hydraulic
servo system due to the requirement performance such as percent overshoot, settling time, rise time
and zero steady state error. This good result will directly benefit industries that use electro hydraulic
system as their actuator for production machines
