精确定点归航翼伞控制系统的研究

Guidance navigation & control system for precision fix-point homing parafoil

采用嵌入式归航控制器、双天线GPS定位定向仪、无线数传机、大力矩直流伺服电机等设备,自主设计归航控制、落点预置、遥控通讯和GPS数据处理等软件,研制具有自动归航和人工遥控归航2种工作模式的精确定点归航翼伞控制系统。其中,在自动归航模式下系统根据GPS收到的位置航向等信息控制翼伞向预设目标点靠近;而在人工遥控的模式下,由地面操作人员通过地面控制计算机发送无线遥控指令控制翼伞归航。对该控制系统进行系统地面联试和负载试验的验证。研究结果表明:本研究提供的控制系统满足了可控翼伞定点归航的需要。

Using embedded navigation control device,double-antenna GPS device,unwire data transporter and big moment direct current electromotor,navigation control software,landing point pre-setting software,remote control communication software,GPS data converse software was designed independently.Precision fix-point homing parafoil control system which has two working modes of automatic homing and manual remote control was developed.In the automatic homing mode,system controls parafoil approaching the pre-setted target point.And in the manual remote control mode,ground operating person sends remote control instructions to operate parafoil returning using ground control computer.And the control system was validated by association test and load test,respectively.The result indicates that the control system our research provided fulfilled the demand of controllable parafoil fix-point homing.
