Gantry-Type XYZ-Style Linear-Motor Control Experiment Platform

1.      Platform Introduction

Linear motors can be regarded as a structural variant of rotating motors. With the rapid development of automatic control technology and microcomputers, linear-motion drive devices consisting of a traditional rotating motor and a transformation mechanism can no longer satisfy the requirements of modern control systems. Compared with rotating motors, linear motors have the advantages of a simple structure, high positioning precision, fast reaction speeds, high sensitivity, and good servo performance. 

Linear motor control technology studies can be basically classified into three aspects: 

  1. Traditional Control Technology; 
  2. Modern Control Technology; 
  3. Intelligent Control Technology.

This platform uses the gantry-type XYZ-style linear-motor as the controlled object and provides a fast control prototype verification platform based on Matlab Simulink design. This system is simple-structured, easy to operate, and particularly suitable for control-specialty postgraduates’ scientific research development and use. Common control methods include: self-adaptation control, sliding mode variable structure control, robust control and intelligent control. It mainly combines fuzzy logic and neural networks with existing mature control methods such as PID and H∞ control for mutual complementation to achieve better control performance.
