基于Matlab的飞艇控制半物理实时仿真系统设计

由于飞艇惯性大，响应时间长，机动性低，为了提高机动性，采用基于LMI线性矩阵不等式的方法设计控制律算法，为了验证飞艇控制律的性能，在Matlab的XPC实时仿真平台基础上，搭建半物理仿真平台，研究了宿主／目标机和飞控计算机及地面操作站之间通过串口和反射光纤组成的反射内存网实现宿主／目标机和飞控计算机及地面操作站之间的信息通讯。系统实时仿真的结果表明，该系统能直观有效地验证各种控制律算法的性能，为飞控算法移植到工程应用中提供了有益的参考。

Matlab-based design of semi-physical real-time simulation system for airship control

As the large airship inertia,long response times,low mobility,a method based on linear matrix inequality(LMI) technology was adopted to design the control law algorithm and to improve its mobility.In order to verify the performance of the airship control law,a semi-physical simulation platform was built on the basis of the XPC real-time simulation platform in Matlab,and the reflective memory network composed of the serial port and the reflected optic filler between the host/target and the flight control computer/ground station to achieve the information communication between the host/target and the flight control computer/ground stations.The real-time simulation results show that the system can intuitively and effectively verify the performance of various control law algorithms.It provides a useful reference for engineering applications of the flight control algorithms.
