【摘要】 介绍了用滑动模态变结构控制对坦克水平稳定器进行设计的方法。滑动模态变结构控制主要由求取切换函数及变结构控制两部分组成。采用最优化方法设计的切换函数,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。更多还原

【Abstract】 Sliding mode variable structure control is applied to design horizontal stabilizer for tanks. Sliding mode variable structure control consists two parts:switching function and variable structure con- trol.Switching function with optimization method ensures stable sliding mode.With power reaching rule method the variable structure control makes the trajectory outside the switching surface reach the switching surface in limited time.Based on this simulation experiment is made.The simulation result shows that the unit step response of the system is fast without overshoot with stable error being zero and steady tracking is possible with ramp input.更多还原
