Abstract:

The paper deals with the structure of the adaptive control electro-hydraulic servo-system (EHSS) with external load disturbances, practical verification of the identification, and control algorithms. The electro-hydraulic servo system composed of a servo-cylinder controlled with a servo-valve is discussed. It is a strongly nonlinear object with parameters changing over time. Adaptive adjuster parameters were determined by means of current identification resulting in the parametric model. Identification was conducted on the basis of measurement of the controlling size and regulated size objects. The identified model of the object was applied to carry out the on-line synthesis of the proportional–integral–derivative (PID) controller. The selected problems connected with obtaining the algorithm of adaptive control are presented. The computer program for implementing the algorithm with numerical simulation and identification of the control physical model object were calculated. The aim of the research was to examine the effectiveness of the adaptive control method in an electro-hydraulic servo system, both theoretically and experimentally.
