线性随机系统有限时域鲁棒协方差控制的凸优化

Convex optimization for finite horizon robust covariance control of linear stochastic systems

Georgios Kotsalis, Guanghui Lan, Arkadi Nemirovski

摘要:

本文研究了离散时间部分可观测线性系的有限时域鲁棒协方差控制问题,该系统受随机零均值噪声和确定性但未知的扰动的影响,这些扰动被限制在所谓的ellitopic不确定集(例如,以原点为中心的椭圆体/椭圆柱面的有限交点)。通过平均凸二次不等式、平均值上的线性不等式以及预先指定的协方差阵上界,对随机状态控制轨迹施加性能指标。对于这个问题,我们开发了一个计算上易于处理的程序设计仿射控制策略,在这个意义上说,保证上述性能规格的政策的参数作为一个显式凸规划的解决方案。我们的理论研究结果说明了一个数值例子。

英文摘要:

This work addresses the finite-horizon robust covariance control problem for discrete-time, partially observable, linear system affected by random zero mean noise and deterministic but unknown disturbances restricted to lie in what is called ellitopic uncertainty set (e.g., finite intersection of centered at the origin ellipsoids/elliptic cylinders). Performance specifications are imposed on the random state-control trajectory via averaged convex quadratic inequalities, linear inequalities on the mean, as well as pre-specified upper bounds on the covariance matrix. For this problem we develop a computationally tractable procedure for designing affine control policies, in the sense that the parameters of the policy that guarantees the aforementioned performance specifications are obtained as solutions to an explicit convex program. Our theoretical findings are illustrated by a numerical example.
