The paper deals with the structure and drive of the adaptive electro-hydraulic control system and practical verification of the identification and control algorithms. The electro-hydraulic servo system composed of hydraulic cylinder controlled by proportional valves is discussed. The parameters of the adaptive adjuster were determined by means of the results of the current identification of the parametric model. The identification was conducted on the basis of the measurement of the object's controlling size and the regulated size of the object. The identified model of the object was applied to carry out on-line synthesis of the PID adjuster. The selected problems connected with obtaining the algorithm of adaptive control are presented. A computer program implementing the algorithm with the numerical simulation and the identification of the physical model of the control object is worked out. The aim of the research is to examine the effectiveness of adaptive control method in electro-hydraulic servo systems both theoretically and experimentally.
