Abstract
This paper presents a mathematical model of a servo system consisting of a linear electric motor pulling a hydraulic drive valve. An analytical description of its nonlinear traction characteristic, as well as the resulting reaction from the action of the electromagnetic force and the elastic force of the centering spring, is presented. The adaptive laws of control of a servo system and a comparative analysis of the effectiveness of adaptive algorithms with a reference model and those using the motions separation technique are given. Simulation results of the model of the servo system with controllers in the MATLAB/Simulink software package are presented to demonstrate the effectiveness of the proposed approaches in this paper.
