摘要:

本文研究有限时间域下连续时间线性二次调节器的逆最优控制问题,旨在从观测到的最优输入中重构目标函数中的控制代价矩阵、状态代价矩阵和终端代价矩阵。以往研究主要在系统可控且控制代价矩阵已知的假设下,探索状态代价矩阵的恢复方法。受控制代价矩阵未知且需辨识的各类应用启发,本文提出两种重构方法。第一种方法利用反馈矩阵的完整轨迹,建立了唯一恢复的充要条件。为进一步降低计算复杂度,第二种方法利用部分时间点的反馈矩阵,并给出了唯一性的充分条件。此外,本文以更通用的方式研究了状态代价矩阵和终端代价矩阵的恢复问题。与假设系统可控的现有工作不同,本文分析了可控性对问题适定性的影响,并推导了可控和不可控两种情形下未知矩阵的解析表达式。最后,本文刻画了控制代价矩阵待重构与控制代价矩阵作为先验已知这两类逆问题之间的结构关系。

英文摘要:

This paper studies the inverse optimal control problem for continuous-time linear quadratic regulators over finite-time horizon, aiming to reconstruct the control, state, and terminal cost matrices in the objective function from observed optimal inputs. Previous studies have mainly explored the recovery of state cost matrices under the assumptions that the system is controllable and the control cost matrix is given. Motivated by various applications in which the control cost matrix is unknown and needs to be identified, we present two reconstruction methods. The first exploits the full trajectory of the feedback matrix and establishes the necessary and sufficient condition for unique recovery. To further reduce the computational complexity, the second method utilizes the feedback matrix at some time points, where sufficient conditions for uniqueness are provided. Moreover, we study the recovery of the state and terminal cost matrices in a more general manner. Unlike prior works that assume controllability, we analyse its impact on well-posedness, and derive analytical expressions for unknown matrices for both controllable and uncontrollable cases. Finally, we characterize the structural relation between the inverse problems with the control cost matrix either to be reconstructed or given as a prior.
