摘　　要：该文介绍了用滑动模态变结构控制对坦克水平向稳定器进行设计。滑动模态变结构控制主要由两部分组成 :求取切换函数及变结构控制。文章采用最优化方法设计切换函数 ,保证滑动模态稳定 ;用幂次趋近律确定变结构控制 ,使切换面以外的相轨线于有限时间到达切换面。在此基础上又进行了仿真实验。仿真结果显示系统单位阶跃响应快速无超调 ,稳态误差为零 ,斜坡输入下能平稳跟踪。该设计方法优于传统设计方法 ,满足各项技术指标要求 ,能够有效提高坦克稳定器性能 ,为稳定器设计提供了一种切实可行的方法。Sliding mode variable structure control is applied to design horizontal stabilizer of tanker in this paper. Sliding mode variable structure control consists two parts: getting switching function and variable structure control. It gets the switching function with optimization method to make the sliding mode stable; with power reaching rules method it also gets the variable structure control so that the trajectory out of the switching surface can reach the switching surface in limited time. Based on this the paper also gives some simulation curves. The simulation shows that the system presents quickness without overshoot under unit step response and steady track with ramp input. This design is better than traditional ones and satisfies tactical requests . This method is practical for design of stabilizer and can improve the capabilities of stabilizer of tanker.
