数字式姿态控制系统的离散变结构控制

Discrete VS Control of Digital Missile Attitude Control System

随着数字计算机的发展,数字式控制器已成功地应用于导弹姿态控制系统当中。文中针对数字式导弹姿态控制系统,通过对离散变结构控制的研究,提出了一种姿态控制系统的离散变结构控制方法,设计了变结构控制律。该变结构控制律在实现姿态控制系统鲁棒控制的同时,有效地抑制了传统变结构控制的抖振现象。仿真结果验证了文中方法的有效性。

Digital controller has been already applied to missile attitude control system with the development of computer. On the research of discrete VS control and digital missile attitude control system, a discrete VS control approach is proposed to be applied to the attitude control system. This VS control law implements robust control of attitude control system, at the same time, it overcome the chattering problem. The effectiveness of this approach is showed via the results of simulation.
