| 摘 要： | 针对一类不确定多变量线性系统,提出一种对数型快速Terminal滑模变结构控制方案,设计了对数型非线性Terminal滑模超曲面及其相应的变结构控制律.研究结果表明:系统状态在有限时间内收敛至Teminal 滑模面上,随后系统保持在滑模面上并在有限时间内收敛到平衡点.与普通快速Terminal滑模相比,在滑模面上能以更...

| Abstract: | A logarithmic fast terminal sliding mode control methodology for a class of uncertain multivariable linear systems was proposed in this paper.The logarithmic nonlinear terminal sliding mode hypersurface and variable structure control law were designed.The results showed that the system state variables could be driven to reach the sliding hypersurface in finite time, then retain on the sliding hypersurface and converge to the equilibrium point in finite time.The time to reach the equilibrium point in the sli... |
