This work deals with the investigation of the effect of a more recent, powerful control algorithm, called Pseudo Derivative Feedback, PDF, on the performance of a hydraulic servomechanism. The controlled system behavior is theoretically evaluated by developing a mathematical model for the controlled system and by using a computer simulation program. Also, the experimental measurement of the system dynamic performance is conducted. The developed simulation program is validated by comparing theoretical and experimental results of the system response. The simulation program is used to deduce a transfer function for the studied servomechanism. Once the transfer function of the controlled system is obtained, the control algorithm implementation is performed. To define the advantages of the proposed control algorithm, its output is compared to that of the already existing unity feedback system. Finally, A proposal for the design of the PDF controller is presented.
