Design and Implementation of an 8-axis Cooperative Working Servo Motor Control Card Based on CPLD

摘要

This article introduces a design of an 8-axis cooperative working servo motor control card based on ISA Bus using Altera CPLD series device and MAX+plus II software for the control of a 50m model of Large Radio Telescope(LT) cable suspension feed system. Here, the method of design and implementation are presented. Through simulation with software and verification with experimentation, the result satisfies the accuracy. Compares with the system based on traditional design model, it improves the reliability of the system and possesses a briefer structure. Even, it has the flexibility of expansion.
