中文摘要: 本项目将研究受有色噪声干扰的机械系统的建模和控制问题。完善随机机械系统的稳定性理论: 如指数稳定性,L2稳定性,RDE切换系统的稳定性。将随机噪声视为平稳有色噪声,构造一类随机拉格朗日系统和一类随机哈密顿系统。对于所建立的模型,采用反推,耗散和无源技术,设计控制器使系统达到某种意义下的渐近跟踪,并设计最优控制器使期望的性能达到最优。本项目的研究结果可以应用到多种复杂环境中的控制问题,这些环境如起伏道路上颠簸的车厢,海浪上抖动的船体。

英文摘要: This project will research the modeling and control problems for mechanical systems subjected to the colored noise disturbance. The stability theory of random mechanical system should be improved, such as exponential stability, L2 stability, the stability of RDE switched systems. By regarding random noise as stationary colored noise, a class of random Lagrange systems and a class of Hamilton systems are constructed. For the constructed models, by using the backstepping, dissipative and passive, the controllers are designed such that the systems achieve asymptotic tracking on a certain sense, and the optimal controller is designed to make the desired performance to achieve the optimal. The research results of this project can be applied to a variety of control problems in complex environment, such as an automobile riding on rough road, a ship on waving sea.
