关于随机分布参数系统的变结构控制研究

Variable structure control for systems with stochastic distributed parameters

研究了一类It型随机时滞分布参数系统的滑动模控制问题,设计了该系统的变结构控制器,证明了系统的滑动模运动的存在性,并分析了在滑动切换面上滑动模控制系统关于不确定量的不变性特征及运动稳定性.与相关论文相比,所获结论与扩散系数相关,在实际应用中更具实践意义.运用文中方法,类似论文结论均可进行改进.

We study into the sliding mode control of Ito-type stochastic time-delay system with distributed parame-ters,design the variable structure controller and verify the existence of sliding-mode movement in this paper.At the same time,the invariable property and moving stability are analyzed for sliding-mode control system with uncertain variables on sliding switching surface.Compared with previous studies in this aspect,the conclusion achieved in this paper is correlated with diffusion coefficients and thus has significance in practical application.Conclusions of many similar papers can be improved and extended by using methods proposed in this paper.
