摘要
在对已有导航仿真系统研究分析的基础上,针对现有导航仿真系统的缺陷,设计了1种基于X-Plane飞行模拟软件的分布式组合导航仿真系统。该系统基于局域网设计,利用X-Plane来实时动画模拟飞机动力学、运动学特性,通过用户数据报协议(UDP)通信协议进行各分系统之间的数据传输;针对常规PID(比例、积分、微分)控制在无人机控制方面响应时间慢,动态性能差等不足,设计了智能PID控制。全数字仿真结果表明本系统控制稳定,适应性强,且系统具有实时性、通用性、可重复性等特性,可以满足各种组合导航系统的仿真需要。
Based on study of existing navigation simulation systems and their defects,a distributed integrated navigation simulation system is proposed based on X-Plane flight simulation software. The system simulates the aircraft dynamics and kinematics characteristics using X-Plane. The data among the subsystems is transmitted based on the user datagram protocol （UDP） communication protocol and local area network （LAN）. Intelligence PID control is designed aimed at the deficiency of regular proportion integration differentiation（PID） control used for unmanned aerial vehicle （UAV）control such as long response time and bad dynamic performance. Digital simulation results show that the system has good performance of stability and adaptability and meets the need of simulation of various integrated navigation systems.
