基于微小型弹体的舵机控制电路的设计

Servo Control Circuit Design Based on Miniature Projectile

提出了一种基于FPGA的舵机控制电路在微小型弹体中的应用方法,对基于FPGA的舵机控制硬件电路及逻辑设计进行了详细阐述,并说明了该控制电路的具体应用实现;该设计采用FPGA作为核心控制元件、舵机作为基本的执行机构搭建了具体的硬件电路;设计了舵机控制逻辑且根据此逻辑编写了对应的程序;对硬件电路进行了调试;经过大量的试验,结果表明该电路可以实现舵机(尾翼)0°～180°范围内任意角度的平滑偏转,进而控制微小型弹体姿态的偏转,长期稳定的工作,且已成功应用到了某项目的姿态控制试验中。

This paper presents a FPGA-based servo control circuit in the micro and small missile application method,FPGA-based servo control circuits and logic design are described in detail and describes the specific application of the control circuit to achieve.This design uses FPGA as the core control device,steering gear as the basic body structure;designed servo control logic and prepared the corresponding procedures;according to this logic circuit debugging hardware.After a number of tests,the results show that long-term stability of the circuit can work,and has been successfully applied to the attitude control of a test project.
