The hydraulic system finds application in a broad range of industrial tasks like mobile equipment, material handling, and automotive testing. The system’s dynamics are highly nonlinear and include the high uncertainties range of the model as well as outward disturbances. The PID controller has been built to reach minimum steady-state error for the output displacement as well as enhance the position transient response. The PID controller parameters employ the Ant Colony Algorithm technique for tuning as well as enhancing the servo-hydraulic system’s output. In this paper ant colony algorithm will tuning parameters of PID controller in order to enhance the servo-hydraulic system output. The result after ant colony algorithm tuning comparing with classical PID controller show the response of the servo-hydraulic system was interesting enhancement however the unexpected disturbance signals for different signal references were added to prove the robustness effective and validity performance.
