摘要

研究了具有乘性随机传感器不确定性的非线性非完整系统的镇定问题。与已有的非线性非完整系统的研究结果相比,本文考虑了随机噪声对传感器的影响。具体而言,通过采用反步法和输入状态标度技术,提出了一种新的控制设计方案,该方案合理地设计了控制增益,同时处理传感器噪声和非线性函数。利用随机分析的工具,验证了闭环系统几乎肯定有唯一的全局解,其原点是均方稳定的,并且状态几乎肯定可以被调整到零。最后,给出了两个实例来验证所提出的控制方案。

Stabilization of nonlinear nonholonomic systems with multiplicative stochastic state sensing noise
This paper studies the stabilization of nonlinear nonholonomic systems with multiplicative stochastic sensor uncertainty. Compared with existing results on nonlinear nonholonomic systems, this paper considers the influence of stochastic noise on sensors. Specifically, by applying the backstepping method and the input-to-state scaling technique, a new control design scheme is developed in which the control gain is appropriately designed to deal with sensor noise and the nonlinear functions simultaneously. By employing tools from stochastic analysis, it is verified that the closed-loop system almost surely has a unique global solution, that its origin is mean square stable, and that the state can almost surely be adjusted to zero. Finally, two examples are presented to verify the proposed control scheme.

期刊介绍: Founded in 1981 by two of the pre-eminent control theorists, Roger Brockett and Jan Willems, Systems & Control Letters is one of the leading journals in the field of control theory. The aim of the journal is to allow dissemination of relatively concise but highly original contributions whose high initial quality enables a relatively rapid review process. All aspects of the fields of systems and control are covered, especially mathematically-oriented and theoretical papers that have a clear relevance to engineering, physical and biological sciences, and even economics. Application-oriented papers with sophisticated and rigorous mathematical elements are also welcome.
