空间飞行器的非线性变结构控制

首先给出了一种空间飞行器的非线性动力学模型，通过变换可以把它分解成若干个子系统，然后对每个子系统进行分散变结构控制，从而有效地解决了空间飞行器的非线性控制问题。仿真结果表明，该方法对于具有参数不确定性的非线性系统可以获得非常理想的结果。而且控制算法简单，易于实现，适于在空间飞行器上计算机容易有限的条件下应用。

Spacecraft Nonlinear Variable Structure Control

A spacecraft nonlinear dynamics is decomposed into three subsystems and the decentralized hierarchical variable structure control system design scheme for every subsystem solves the problem of spacecraft nonlinear control well. Simulation results show that this method can obtain satisfying results. Furthermore, the control algorithm of this scheme is simple enough to be successfully applied to the case of the limited computer memory on spacecraft.
