中文摘要: 本项目拟构建星载TDICCD随机振动控制系统的数学模型,首先运用随机激励下的耗散汉密尔顿系统理论,构建外部振动激励下的耗散的汉密尔顿系统,运用伊藤随机微分理论和随机平均法导出平均系统,随后建立不确定性系统的随机最优控制问题,针对该随机最优控制问题,由随机动态规划原理得到不确定性系统的动态规划方程,通过求解该动态规划方程得到最优平均控制策略。最后通过相关仿真软件平台实现星载TDICCD随机振动控制系统的仿真,并进一步选定和开发相关软硬件构建星载TDICCD随机振动控制系统实验平台,最终进行验证振动抑制效果并获得有价值的理论和应用成果,为本项目的实际工程应用打下必要的理论和技术基础。

英文摘要: The project intends to build the mathematical model of the stochastic vibration control system for satellite TDICCD. Firstly, it is built the dissipation Hamilton system with the external vibration excitation by the Hamilton system theory, and then it is derived the average system with Ito stochastic differential theory and stochastic averaging method. Secondly, it is built the stochastic optimal control problem of the uncertainty system, which can get the dynamic programming equation by the stochastic dynamic programming principle, this equation can be solved to have the optimal control strategy on average. Finally, it is achieved the simulation of the stochastic vibration control system for the satellite TDICCD by the simulation software, and built the experimental platform of the stochastic vibration control system for the satellite TDICCD to select and develop the related software and hardware. Ultimately, the vibration suppression effect can be validate by the experimental platform, and get the valuable results of the theoretical and the application, which is the necessary foundation of the theory and technology to the practical application.
