The purpose of this project is tod etermine suitable methods to test the steady and dynamic state of EHS160 Electro-Hydraulic Servomechanism machine.By doing so the response of the electro-hydarulic servomechanism machine in both states can be tested.Servomechanism is an automatic control system which is designed to controlmechanical parameters such as velocity by following a given variation intarget values. Using some form of feedback, results from the control operation are compared against target values, and corrective operation will be madeto produce the desired result.The feedback EHS160 Electro-Hydraulic Servomechanism machine that is used for experiments to test the peculiar characteristics in hydraulic system.Each experiment is accompanied by relevant theory, guided by important concepts. The experiments are represented is steady and dynamic state characteristics of the hydarulic, electrical components and servo loops. For steadystate characteristics derived, it includes gain, stiffness and error constants. The various symbolic and graphical techniques, including the Bode plot,for analyzing and synthesising servo behaviour are tested using time dependent characteristics experiments. The scope of this project is as follows :(1) Explore hydraulic and control system on the electro-hydraulic servomechanism. Then, select a suitable equipment to collect data on voltage, time required, etc and determine the type of output signal. (2) Prepare and analize questionnaire related to electro-hydraulic servomechanism (3) Install the thermocouple to the best position to the mechine oil tank and measure the temperature of the fluid. This reason is to prevent the temperature from exceeding the indicated 40'C when the machine operate fora a long duration. (4) Determine the behaviour of the machine at steady dna dynamic state, by carrying out experiments ad and collecting the necessary data. (%) Use the 'matlab' computer program to analise the result of the experiments. (6) Select a few suitable experiments to test the steady and dynamic state of the machine.
