基于FPGA的星载步进电机控制电路设计
Design of stepper motor control circuit for satellitebased on FPGA
摘要
Abstract
A design of a circuit controlling stepper motors in a wide range of moment for special characteristics of long in-orbit operation and the difficulty to replace in space equipments was proposed. This design utilizes FPGA,Xilinx chip XC3S400-208, as the core control chip and LMD18200 as the driving chip of stepper motors. On the basis of a description of the circuit, the problem of the increase of resistance moment and the solutions of output moment adjustment in space equipments by PWM control and impulse frequency were discussed.Tests verified that the design′s maximum value of output moment in range makes moment margin reach 4 and the range of adjusting matches the requests of space equipments.关键词
