CONTROL TRACKING ELECTRO - MECHANICAL OF LEAD SCREW SYSTEM USING SERVO MOTOR APPLICATION IN MACHINE TOOLS BASED ON SLIDING MODE CONTROL METHOD

Abstract

This paper presents the research synthesis method applied in electrome-chanical tracking system, lead screw control using AC servo motors applied in machine tools, based on the sliding mode control method and the state observer. Control rules are capable of compensating for perturbation components, with a state observation built in to evaluate and compensate for uncertain nonlinear components. Then the chattering reduction techniques of sliding mode surface are proposed to improve the quality systems. The research results were simulated in Matlab Simulink, the experimental and practical process with the lead screw system control application model of machine tools. The research results obtained are also the basis for calculating, designing and manufacturing intelligent electric drive systems for industrial applications.
