摘　　要：对一类采用过载控制的飞行器的高度控制系统,采用Lyapunov函数方法,进行基于过载受限的饱和控制器设计。该方案使得不同初始状态与控制目的的高度控制系统,均能在输入受限的条件下,收敛到系统原点领域。高度控制系统是一类非线性系统,文中通过构造Lyapunov函数方法,确保了系统的稳定性。由于控制律采用的是饱和控制形式,因此从根本上解决了输入受限问题。最后仿真结果表明了该方案的有效性。By adopting Lyapunov function theory, a saturating controller with limit overload was designed for the altitude loop of a kind of aircraft with overload control. The method can converge the state of the altitude control system to equilibrium point with different initial states and aims of control under the condition that the input is limit. The altitude control system is a kind of nonlinear system , the stability of which was ensured by constructing Lyapunov function, and the limit input problem was solved thoroughly by adopting a kind of control law with saturations. Finally, the simulation results show the excellent control effect of the proposed method.
