摘要

针对坦克炮控系统中存在齿圈间隙、摩擦力矩和参数漂移等多种非线性因素造成系统驱动延时、换向振荡和低速"爬行"等问题

设计了一种基于扩张状态观测器(ESO)的炮控系统串联滑模控制器。首先

利用系统内部可测信息

将炮控系统分解为

个串联的一阶子系统;然后

引入ESO估计各子系统的不确定性。在此基础上

基于backstepping递推思想

分别针对各子系统设计滑模控制器

并逐步向后递推

构成炮控系统串联滑模控制器。试验表明

该方法能够很好地抑制各种非线性因素的影响

有效地改善系统控制性能。由于各子系统均为一阶系统

ESO和滑模控制器的设计大为简化

易于工程实现。此外

该方法还有效地抑制了传统滑模控制的抖振问题。

Abstract

For problems of system driving delay

commutation surge and dithering at a low velocity caused by nonlinearity such as backlash

friction and parameter varieties in a system

a series sliding mode controller for a tank gun control system based on Extended State Observer ( ESO) was designed. Firstly

depending on the measurable signals

a gun control system was decomposed to

first-order subsystems in series

and ESO was introduced to estimate the uncertainty of each subsystem. Then

by adopting a 'backstepping method'

the sliding mode controllers were designed for each subsystem and made up these sliding mode controllers in series for the gun control system. The examination result shows that the method can restrain the influences caused by the diversified nonlinearity and can improve the system performance effectively.The design of ESO and sliding mode controller is simplified and prove to be realized in engineering because of the design of each first-order subsystem. Furthermore

this method overcomes the dithering problem excisted in traditional systems effectively.
