摘要/Abstract

摘要： 针对随机噪声具有未知协方差的一类随机非线性时变滞系统,研究了输出反馈自适应控制问题.利用反推设计技术,构造性的给出了一个基于观测器的控制器和仅与输出相关的自适应律,保证了闭环系统是概率意义下全局渐近稳定的,所设计的观测器和自适应控制器是不依赖于时滞的.仿真例子验证了该控制方案的有效性.

Abstract: The output-feedback adaptive control problem was investigated for a class of stochastic nonlinear time varying delay systems driven by stochastic noise of unknown covariance. By utilizing the backstepping design technique, acontroller based on observer and the adaptive law only correlated with output was constructively presented to guarantee that the closed-loop system is globally asymptotically stable in probability, where the designed observer and adaptive controller are all independent of time-delay. A simulation example demonstrates the effectiveness of the control scheme.

Key words: stochastic nonlinear time varying delay systems, back-stepping, output-feedback stabilization, globally asymptotically stable in probability
