Small-Power Motor Motion Control Experiment Platform

1.      Platform Introduction

The three-phase AC asynchronous motor control experiment platform is mainly applied in AC asynchronous motor motion control experiments. It can provide a basic verification platform and innovative experiment platform for courses such as motor and drive, motion control, control system simulation based on Matlab, etc. This system features a simple structure and convenient operations, and is particularly suitable for students’ experimentation verification of self-developed innovative control algorithms.

The platform uses the Links-LabBox fast prototype simulator as the speed loop controller. Users can flexibly conduct various types of open/closed-loop control algorithm design and verification experiments. Besides, the platform provides a motor pairing platform, in which an AC asynchronous motor (drive side) and AC permanent-magnet synchronous motor (load side) realize coaxial pairing through a coupler. By setting different load-side disturbance moments on the motor pairing platform, changes in the speed and electric current of the drive-side AC asynchronous motor can be observed, and thus the control algorithm can be further optimized.

  1. Modular Design: Adopts the idea of modular design with a clear system structure;
  2. Motor Pairing Platform: As the controlled object, the three-phase AC asynchronous motor, equipped with an encoder, can realize accurate speed closed-loop control; as the load in this pairing, the AC synchronous servo motor can realize accurate reverse-moment loading (constant moments, pulse moments, continuously varying moments, etc.);
  3. Friendly Development Environment: the system supports the design of asynchronous motor control algorithms based on Matlab Simulink and supports the smooth transition from digital simulation to motor physical control;
  4. Excellent Platform Timeliness: The controller adopts the solution of X86 hardware running on the VxWorks real-time system, and its timeliness can reach the 100us level;
