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。
Due to its large inertia, long response time and low maneuverability, in order to improve the maneuverability, a control law algorithm based on LMI linear matrix inequality is designed. In order to verify the performance of the airship control law, based on Matlab’s XPC real-time simulation platform, The semi-physical simulation platform is used to study the communication between the host / target computer, the flight control computer and the ground operation station through the reflective memory network consisting of serial port and reflective fiber between the host / target computer, flight control computer and ground operation station. The results of real-time system simulation show that the system can verify the performance of various control law algorithms visually and effectively, which provides a useful reference for the flight control algorithm to be transplanted to engineering applications.
