摘要:

本文研究在有限时间范围内,从给定初始状态协方差出发,具有加性噪声的线性随机系统所能达到的终端状态协方差集合。对于离散时间系统,给出了可达状态协方差集合的完整刻画。对于连续时间系统,我们给出了可达状态协方差集合的一个上界。此外,对于线性离散时间和连续时间系统,均提供了有限时间范围内状态协方差能控性的充分必要条件。

英文摘要:

This paper studies the set of terminal state covariances that are reachable over a finite time horizon from a given initial state covariance for a linear stochastic system with additive noise. For discrete-time systems, a complete characterization of the set of reachable state covariances is given. For continuous-time systems, we present an upper bound on the set of reachable state covariances. Moreover, for both linear discrete-time and continuous-time systems, necessary and sufficient conditions are provided for the controllability of the state covariance over a finite horizon.
