Adaptive Algorithm for Servo System Using Linear Electric Motor

This article aims to build the construction of a mathematical model of a linear motor for moving the valve of an electro-hydraulic drive. First, an analytical description of its non-linear traction characteristic is given as well as the resulting reaction from the action of electromagnetic force and the elastic force of the center spring. Second, the Adaptive algorithm of servo control based on the Lyapunov theorem is built and an analysis of the effectiveness of the adaptive algorithm with the change of the servo system’s parameters. Simulation results on the model of the servo system with the controller in the MATLAB-Simulink software package are presented to demonstrate the effectiveness of the proposed approach in this paper.
