Syntesis of automatic control system of the rotor axial displacement of the mechatronic motion module

The paper is devoted to the development and the investigation of scientific and practical solutions of the centering problem of the rotor spatial position of the mechatronic motion module used in high-precision processing systems. The existing and widely used methods of eliminating mass unbalances at present are considered. A new approach to solving the problem of stabilizing the rotating element of the mechatronic motion module based on the active current updating of the spatial position is offered. The paper considers the structure of the proposed approach, methods of synthesis of control loops states in the active stabilization system. It presents the results of the simulation, confirming the efficiency of the proposed approach.

I. Introduction

The direction of using the mechatronic motion modules in different fields of science and technology increases every year. Therethrough, there are new requirements for their operation. But a primary consideration is an unbalance of rotating elements impairing the performance of any electromechanical system. Particularly, differences between the actual axis of rotor rotation and the projected axis of rotation during the operation process may lead to vibration. That causes excessive wear of bearing assemblies, spindles or mounting faces. Mechanical oscillations can lead to the occurrence of the resonance effect and cause massive fracture of the mechanism.
