部分观测的随机线性二次最优控制

Stochastic Linear-Quadratic Optimal Control with Partial Observation

Jingrui Sun, Jie Xiong

摘要:

研究了部分可观测线性动力系统的一类二次型最优控制问题。与全信息情况相反,控制需要适应于由观察系统产生的过滤,而观察系统又受到控制的影响。在这种情况下,由于过滤不固定,变异方法失败。为了克服这一困难,我们使用状态过程的正交分解,将成本泛函写成两部分之和:一部分是控制和滤波过程的泛函,另一部分与控制的选择无关。第一部分具有类似于完全信息问题的数学结构。通过完成平方,它表明,最优控制是通过滤波过程的反馈表示。同时也明确地得到了最优值。

英文摘要:

The paper studies a class of quadratic optimal control problems for partially observable linear dynamical systems. In contrast to the full information case, the control is required to be adapted to the filtration generated by the observation system, which in turn is influenced by the control. The variation method fails in this case due to the fact that the filtration is not fixed. To overcome the difficulty, we use the orthogonal decomposition of the state process to write the cost functional as the sum of two parts: one is a functional of the control and the filtering process and the other part is independent of the choice of the control. The first part possesses a mathematical structure similar to the full information problem. By completing the square, it is shown that the optimal control is given by a feedback representation via the filtering process. The optimal value is also obtained explicitly.
