摘要
本文研究了一类具有未知时变时滞的随机非线性系统的输出反馈跟踪控制问题。系统中的扩散项和漂移项不仅依赖于输出,还依赖于不可测量的状态和未知的时变时滞。对于具有时变时滞的随机非线性系统,本文通过引入坐标变换和齐次占优技术,设计一个基于观测器的输出反馈控制器,使得跟踪误差能调节到零的任意小邻域内。仿真结果验证了所提方案的有效性。
The output-feedback tracking control problem for a class of stochastic nonlinear systems with unknown time-varying delays was studied in this paper.The drift terms and diffusion terms depend not only on the output signal,but also on the unmeasurable states and unknown time-varying delays.For the stochastic nonlinear system with time-varying delays,by introducing coordinate transformation and homogeneous domination technique,an observer-based output-feedback controller was designed so that the tracking error could be adjusted to any arbitrarily small neighborhood of zero.The effectiveness of the proposed scheme was demonstrated by the simulation.
