基于CAN总线和PCC的多电机消隙天线控制系统

The Multi-motor Anti-backlash Antenna Control System Based on CAN and PCC

CAN总线是目前世界上应用最广泛的现场总线之一，在我国得到越来越多的应用。多电机消隙控制模式常用于大型雷达天线控制系统，主要用以消除其转台的齿轮间隙。本文以基于CAN总线和PCC的高精度多电机消隙天线控制系统为背景，着重描述了该系统的控制原理和软、硬件设计。

At present, Controller Area Network （CAN） is one of the most widely used fieldbus in the world, and it has been more and more applied in our country. The muhi-motor anti-backlash control mode is commonly used in large size radar antenna control system mainly for eliminating gear clearance of its rotary table. Against the background of the high-precision multi-motor anti-back- lash antenna control system based on CAN and PCC, the paper puts emphasis on the description of the control principle and the hardware and software designs of the system.
