非线性飞控系统仿真视景演示研究与实现

The Simulation Demo System of Nonlinear Flight Control System

未来新一代战机控制系统必然要采用非线性控制系统。文中首先采用反馈线性化理论设计了非线性飞控系统,进一步设计了非线性飞控系统仿真视景演示平台。视景演示平台能够演示飞行过程中飞机的状态参数变化,直观地给出飞行过程姿态变化、飞行轨迹等,为非线性飞控系统的仿真验证提供了方便、直观的手段。

One of characters of next generation fight aircraft is supermaneuver ability, and the control system of next generation fight aircraft must be nonlinear control system. In the paper, the application of feedback linearization in the flight control is described firstly, then the simulation demo system of nonlinear flight control system is designed. The flight states transformation of attitude and orbit etc can be demonstrated visually. So the simulation demo system provide a convenient and visual tool for the nonlinear flight control system simulation.
