METHOD FOR CONTROLLING MULTI COMMAND TYPE SERVO MOTORS USING MATLAB

Tóm tắt

This study proposes a method to control multiple command type servo motors (CTSM) using Matlab. CTSM that was used in this study was a Futaba RS301CR-F3 motor which can be controlled multiply by a set of command lines through RS485 interface using Matlab. In order to setup the connection between Matlab and RS485 interface, an USB serial adapter was used. The advantages of servo command type motor are high speed, accuracy, and built-in feedback system. The control functions for motors are written in Matlab M-file. Then, a Graphic User Interface (GUI) was created to manually control motor’s positions and visualize motor’s actions. The system has been tested and showed its properly working behavior. As far as we know, so far this is the first work to use Matlab to control CTSMs with only a single RS485 port. This is a new approach for engineers to build a big system with multiple driving mechanisms which use a single RS485 port through USB serial adapter.
