AI中文摘要:

本文针对线性伊藤扩散过程,引入了一种鲁棒W-无穷最优控制框架,采用加权索伯列夫空间性能度量。由于伊藤扩散过程的样本路径不可微,该公式利用了期望状态的弱导数。研究开发了一种基于线性矩阵不等式(LMI)的半定规划,用于动态输出反馈综合,且严格的稳定性分析保证了均方最终有界性,同时最小化了最终界。数值示例表明,所提方法能有效实现干扰衰减,且具有快速瞬态性能。

英文摘要:

This paper introduces a robust W-infinity optimal control framework for linear Itô diffusions using a weighted Sobolev-space performance measure. Because the sample paths of Itô diffusions are nondifferentiable, the formulation leverages the weak derivative of the expected state. An LMI-based semidefinite program is developed for dynamic output-feedback synthesis, and a rigorous stability analysis guarantees mean-square ultimate boundedness with minimized ultimate bound. A numerical example demonstrates that the proposed approach provides effective disturbance attenuation with fast transient performance.
