    Performance Comparison of Particle Swarm and Transit Search Algorithm for Position Control of Electrohydraulic Actuator
    (2023) Yisak Tagese
    Electro-hydraulic servo actuator system is widely used in process industries due to their strong power-to-weight ratio, stiffness response, high and good speed, and substantial drive system The electro-Hydraulic actuator system's nonlinearities time-varying features, and uncertainties have made it difficult to regulate the system precisely. The best controller would be highly resistant to parameter fluctuations and result in improved performances. This thesis work studies the position control of electrohydraulic actuator system. In this thesis, Fractional order proportional integral Differential controller is employed for the position control of the electrohydraulic actuator system. In the study, the electrohydraulic servo actuator system is divided into different components, which are the spool displacement, flapper valve, and electromagnetic torque motor
